You know, if this adaptive behavior is confirmed with more studies, it would be cool to see you do an additional study on whether nurse sharks already bear this behavior via instinct or if they learn it by observing older, more experienced nurse sharks.
This is so cool. I think I remember you teasing this research all the way back when you and AVNJ made the shark tier list. Congrats on all your hard work. Also, thanks for including the video so we can see the different feeding behaviours of the nurse sharks. Awesome stuff!
Congratulations Kristian and to your co-authors on the publication of your paper. That was a fascinating insight into nurse shark behaviour, and the video was a great break down so that ordinary punters can understand it. I learnt so much about nurse shark behaviour and their biology. Their pectoral fins are incredible!
Congratulations on the publication! I have seen a nurse shark that reversed out of a tight space using the pectoral fins. A larger group of divers showing up crowding the shark a bit, led to the behavior.
SO HAPPY FOR YOU!!! in the process of dealing with my first scientific publication and i know i'm just at the tip of the iceberg but omfg. it's nerve wracking. beyond excited that you've got this accepted and published without getting scooped, and i hope you can find time to celebrate!!!
This is so fascinating. Sharks are so interesting. Thank you yet again for an another amazing video. I love how much I learn by watching your videos. My love and fascination for sharks just grows and grows
Biggest sign a study is proper and scientific - the scientist/paper goes through the limitations of the study. Bring peace to my librarian soul 😌😂👏👏👏🤩🥳
Congrats on the paper! Do you happen to know how strong the currents were in the areas where the BRUVs were deployed? Curious if they were also using their pectoral fins to brace and anchor themselves to the seafloor as a way to remain stationary in the water column as they fed.
Great question JB, we didn’t have a way to measure current on the BRUVs but could occasionally see direction based on floating vegetation. Like you say, station holding has been seen in a few shark species, so it would be interesting to explore this a bit more
Awesome. This was very interesting to see the sharks rolling around trying to get at the best angle. So professional of you to point out the limitations and the future of this type of research. Thanks, great episode. Sparked my inner Biochem geek!
I can’t speak on any shark behavior because I know nothing, which is why I come here and listen to your genius brain regurgitate all the fascinating info about them to us 😁 I can , however, speak to the hours and hours and more hours of reading, writing, editing, testing, observing, and all that goes into getting a peer reviewed research article published and that is a massive amount of time, energy and resilience. So congrats on your publication!🙌🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻🍻
i just clicked onto the video, 1 second in and i pause it just to look at the comments and im seeing a lot of "this is fascinating" and now im excited to watch the video.
Love it every time another piece of research adds to our understanding of the world! More complex and interlinked every day. Also, speaking as one myself, gotta watch the little oddballs, always up to something 😅 and nice footage 👌
I noticed a clip (9:14) where there was a larger shark in the background that was likely more dominant than the nurse shark (maybe a blacktip reef shark but its hard to tell). I was wondering if you accounted for the possibility of changes in the nurse sharks' behavior due to the presence of other more dominant predators nearby?
As a postgraduate student, watching your video during breaks between writing my reports, I can't wait to see more of your research and videos in the future!!!
Look at them silly nurse sharks! 😋So cute! 😍😍 Fantastic footage, and congrats on getting your paper published! 🎉🎉 I hope you have a relaxed holiday period to celebrate /recover! 😂
Wooo! I've been waiting for this since you mentioned it. I loved your paper it was very good. More research of sharks is always good. Also I'm always looking for more papers so if you have any suggestions of good ones to read let me know. 👍
10:20 - No clue what their home ranges look like, but that seems like a potential use for something like AirTags or Tiles. Get a bunch of old phones in waterproof containers w/ batteries/solar panels, set them up in a 3D grid, and use a ROV or similar to tag each shark. I wanted to try this with bushbabies, but the species I was working on are too small for even airtags. Sharks are a bit bigger than 200g though!
Cheers Kristian, I’ve enjoyed your channel since you first started, I’ve always enjoyed your ideals and kinda quirky you (in a good way). I think your paper has some great values, I love seeing the nurse sharks reactions to the BRUVS , all the positions and especially the walking. What a lovely animal, Nurse sharks. Thank you for sharing them with us. I’m in Nevada, nowhere near these lovely fellas but admire them much. Keep up the good work, shell 🐚
I thoroughly enjoy your videos, especially this one explaining your academic publication. I'm sure there's a lot more interesting information in the paper, but I'm glad you gave a very interesting summation (I hate reading research papers, even if I really find the subject interesting; sorry, just can't stay awake reading all that nitty gritty. LOL!). Keep up the great work!
Congrats Christian!!! Could you all test whether the nurse sharks would come to the area for the bait cans if you have bait in it for say a week & then you leave the bait out 1 or 2 days to then go back to having bait? If it worked you could see the same behavior that's not being artificially triggered and possibly some other behaviors never seen. I just wouldn't recommend being in the water with them when they realize there's no food in the canisters.
It’s an interesting idea Michelle, although I suppose on the day where there was no bait, what would the nurse shark be feeding on to perform the behaviours?
I was not expecting my home country or big blue in this video, congrats on your paper, I can say I have been in the same waters with the the same sharks I have never seen them doing the behaviors you mentioned, but i have seen them on the rare occasion "digging" in and around coral heads going for lobsters
Congratulations!! Excellent achievement! This is super exciting and so impressive. As a mother of humans about your age…..I just think how proud your mom must be!?! Well done. I’m proud of you.
Congrats Kristian on your paper, that’s exciting. To answer your question I don’t think they could walk out of water like epaulettes, but maybe steer themselves around the tight parts of the reef. I look forward to learning more on this.
Thanks so much for your time and hard work on this. I absolutely loved hearing more about nurse sharks. Some of this was all new to me like the the relationship between the two types of sharks you mentioned and the fact that the nurse sharks have adoptions in their pectoral fins but I have seen that vertical feeding thing on a documentary before. The other two feeding techniques are completely new to me. The video as a whole was really good and I can't wait to read the paper that you did. I also can't wait to see more of your work great job and thank you again.
Really fascinating. I wonder if their pectoral fins are used when the sea gets choppy. Like anchors so they aren't getting dragged back and forth over coral and sea beds since that's where they spend most of their lives.
This is a super exciting new paper! I can't wait for more research to be done. You did an excellent job condensing information and making it easy and fun to learn about. This video was awesome and I can't wait to hear more about your research in the future, no matter what shark topic it may be
This is fascinating. I definitely will take a look at your paper! I do think they are using their pectoral fins for 'walking' based on the behavior here. It would be helpful in reefs since they can almost work themselves under the coral more than if they just swam at it.
So happy to hear you’ve published Kris! 🎉 This was a very interesting episode and the footage of the different feeding positions just shows that these animals are thinking about different strategies to accomplish a goal. ❤
wooooo! congrats on the paper publish! Looking forward to reading soon :) wonderful research and wonderful video friend. Always love nurse sharks, such sweeties :)
Very cool! Informative and super interesting to this layperson. Congratulations to you and your team! I especially enjoyed learning about their pectoral fins, their anatomy and their use of them. So bendy lol. Such beautiful sharks. Thank you for sharing! I’m having fun binging your shows 😊
Hi! I don't know how else to send this to you, but you may was to do a reaction video to this! It was pretty neat. Two parts I believe. ua-cam.com/users/shorts4VQ0ZlQN_I0?feature=shares
When i lived in the Florida Keys I rented a place right on the water. We used to fish right off the side yard and we frequently caught nurse sharks. It was always a challenge to try to get them off the hook and back in the water. I always wondered if we were catching the same shark over and over.
Congrats on the paper! I'm glad we finally get to see your work. It's so interesting when you get to observe animals problem-solve. Sharks are smarter than we will ever know. Definitely not rubbish. 🤣 it's seriously fascinating how animals adapt and learn to problem solve.
Great work and it is very interesting. Very versatile little sharks. Hopefully more people will follow up or your team will continue to study it to confirm your results.
This is fascinating and I look forward to reading it when not so busy. Hopefully after Spring Cleaning (uuggghhh). Id be interested to find out what else Nurse Sharks and Epaulette Sharks have in common. Great video. Have missed learning about sharks.
Congratulations on your paper Kristian, been following you for a while n proud of you both with your research and presentation of your channel. Keep up the great work and looking forward to seeing more collabs with Hal, a live would be fantastic! 🦈😃
Kristan, the nurse sharks’ seemingly “walking” on their pectoral fins to better position themselves with respect to the bait can reminds me a bit of the behaviour of *another* (albeit considerably smaller) bottom-dwelling Orectolobiforme shark: the less than 1 meter long “epaulette shark.” During low tides, epaulette sharks can use their pectoral fins to “locomote” over the tops of reefs or from one tidal pool to another to escape hypoxia (oxygen-depleted tidal pools) and to find food (small bony fish/crustaceans. I probably should have waited until the END of your video to post this, as your paper indubitably discerns this similarity between these two Orectolobiforme species and answers my questions, but the video of the nurse sharks you showed got me excited, and i simply HAD to type. Question 1: do you think this similarity between nurse sharks and epaulette sharks could indicate that Orectolobiforme sharks could have been one of the first fish species to begin the long evolutionary march from being sea-dwelling creatures to being exclusively terrestrial animals? And, Question#2: do you think this behaviour is more of a purely adventitious anomaly among nurse sharks, and not nearly as “common” as the epaulette shark’s little “strolls” from tidal pool to tidal pool, or might *both* sharks represent a modern vestige of those long, loooooooooong lost fossils of the very earliest stages of Life’s beginning to take the long walk to living entirely on land?
So very cool Kris! I saw the Nurse shark attack video first and then this. So im surprised to see that nurse sharks can go upside down and not go into tonic immobility. Do we know why?
I'm a bit late to the game, but congrats on getting the paper finished and published. I'm an author, and while it's a very different process, I do know how great it feels to finish and publish a project.
Great research Kris. A nice insight in the nurse shark world. Be very proud of yourself. Really gutted to hear you missed that opportunity in the Barharmas. That would have been a spectacular trip for you. I really appreciate your work with the channel and enjoy your content very much. 👊🏻🦈
It sounds really interesting to me. Is there an aquarium with Nurse Sharks that you can use to try out the walking hypothesis ? Maybe put them in water too shallow to swim in and see if they can walk to the deeper water or some food ?
This is great, I used to think that sharks in general have a similar behavior, but thanks to Sharkbytes I know that almost every shark is unique and distinctive, and now with this video I like nurse sharks even more.
This was very interesting and informative. Thank you for sharing your research and doing it in an easy to understand way for a lay person. Glad i found your channel. I'm looking forward to hearing about more of your research in the future. ^_^
I've seen bottom-feeding catfish (plecos) using their fins to position themselves like this when they're feeding if they can't sit flat to rasp on their food. I have a 40 cm / 1 kg pleco as a pet right now and he does all sorts of shenanigans to eat his dinner or slurp on his bits of driftwood (xylivores gonna xylivore)... so this feeding behaviour from the nurse sharks looked totally familiar. Just like my boy Edgar when I give him some courgette.
This is a big reason I was drawn in by the channel. I really love hearing research findings when they're delivered in such an honest way. You are very engaging, even when you get into the "boring details." I think it's an awesome way to keep people listening and engaged. That and waiting for you to make wonderfully bad shark movie bingo cards and discovering the SyFy shark movies catalogue. 😂😂😂
Nurse sharks are awesome! I'm from Miami so the nurse shark was the first ever shark I saw in the wild since they're pretty common down here of course. Learning about them and their "walk" is so cool and the pov of the video is awesome too. And sidenote I love how the baited underwater cameras get abbreviated as BRUV lol.
CONGRATS for getting published. 🤍🦈🤍 What impressed me the most was your description of the nurse sharks pectoral fins! One question that has nothing to do with sharks. Is the orange lamp a Himalayan salt dispenser? I've read that it can help with congested nasal passages amongst other functions. I so want to get one for myself. Excellent episode Kristian!
Yes it’s a Himalayan salt lamp! Fortunately I don’t get many allergies, so I can’t speak first hand but I have heard they’re good for that. I just enjoy the soft lighting, especially in these darker months
Might I suggest trying setting crab traps disguised in corals, set with a tied crustation of some kind, and see if nurse sharks are still performing the same movements? Could also set up "puzzles" similar to what they do with dogs or cats (obviously more simplified and designed for underwater settings) in a research lab. This minimizes impact and influence from other marine animals Overall, congrats on this achievement and well done Also right before watching this I came across a UA-cam short by The Sun about a shark encounter with a kayaker. How do I send it to you?
All interesting ideas here, lots of scope for future research! R.e sending me links, you can always try on twitter (@kjparton) or Instagram (@mrkaijai)
CONGRATULATIONS 👏🏻 🦈💙 I LOVE this Video 😍 The Footage is AMAZING and the Nurse Sharks are STUNNING!! I always find myself wishing that they weren’t so viscous so we could interact with them Safely - where THEY Feel Safe and Comfortable and we feel the same way… but I’m not STOOPID LOL I loved the upside down foraging as well as the using their Pectorals to help position themselves - their Incredible Intelligence is so Intriguing to watch 💙🦈🩵😍💙 Fantastic Work 🙏🏼
Perhaps, it would be interesting to see if they did this. Although I think generally they rely on their powerful suction mouths to just engulf their prey very quickly!
Idk if I’m too late but I think I do have some further hypothesis Is it possible that the sharks are trying to experiment where they could suck the food out of the bruv? They would be more familiar with more complex prey like crustaceans who might have some weaker spots than others or some fish with defensive spines that they might have to find a way to get around so they evolve to try foraging from different angles not just bc of the rock shape which isn’t present in the bruv case but also the preys anatomy. It might also be a more intelligent form of trial and error as well with them trying to see which area of the bruv have holes they can suck the food out of
Interesting, Kris😄, thanks for sharing. How do you decide who does what when you have a number of different co-authors? And do things ever get a little feisty when you disagree on stuff?🤨
I took the lead on this one because it was me who was reviewing the footage. Others work to their skills, some authors focus on stats, others focus on specific aspects of the manuscript (there’s a big section on the fin morphology written by a co-author because that’s his speciality). There’s generally no major feistiness, until it goes to review at the journal. Then it gets a little tense with the anonymous reviewers!
This is really interesting. I presume that shark behaviour is different in public aquariums as they are fed by hand or target more. I do wonder if captive nurse sharks are "lazier" then wild nurse sharks. I know at the deep , tilly used to always be in the same area everytime. Unfortunately they lost tilly not long after they introduced Timothy, he stays in a different spot (he is in the shark tunnel cave). They did find that tilly had eggs when they found her, unfortunately she died over night. (She was my daughters favourite).
After binge watching your videos, I'm wondering whether Nurse sharks are immune to tonic immobility, or whether tonic immobility isn't produced when a shark goes upside down by itself. I'll have to read your paper. Thank you for the interesting videos, and explaining things in layman's terms.
I had a strange encounter with a very large nurse shark on Cat Island. Bahamas. I was snorkeling in 10 - 15 ft and a nurse shark surprised me swimming up from behind and bumping me in the chest and continuing past me. It was 6ft+. I have never seen such a large nurse shark before. It later returned and bumped me again. We were staying on the beach where this occurred and snorkeled many times in this same area.Always mid day. It behaved in what I considered an aggressive manner if encountered. I never approached and always gave it its space. It seemed to have a thing for me. It never bothered my husband. This occurred in Shanna's Cove. Funny you mention Cat Island in another video.
Kristian, highly fascinating. Darwinian, pectoral fin walking into the future? Congratulations on your achievement, your hard-working contribution & for sharing ( sharking it) with us! Cheers!
You know, if this adaptive behavior is confirmed with more studies, it would be cool to see you do an additional study on whether nurse sharks already bear this behavior via instinct or if they learn it by observing older, more experienced nurse sharks.
Would be an awesome thing to look into, we did see a few juvenile individuals doing it, so I wonder if it’s innate!
Great idea!
@@SHARKBYTESfascinating research ❤

And, Question#2: do you think this behaviour is more of a purely adventitious anomaly among nurse sharks, and not nearly as “common” as the epaulette shark’s little “strolls” from tidal pool to tidal pool, or might *both* sharks represent a modern vestige of those long, loooooooooong lost fossils of the very earliest stages of Life’s beginning to take the long walk to living entirely on land?
So very cool Kris! I saw the Nurse shark attack video first and then this. So im surprised to see that nurse sharks can go upside down and not go into tonic immobility. Do we know why?
It's not just you, this is really cool!
I'm a bit late to the game, but congrats on getting the paper finished and published. I'm an author, and while it's a very different process, I do know how great it feels to finish and publish a project.
I read it and it was AWESOME 😎 thanks alot for all you do💜
Thanks for watching and reading Penny!
Great research Kris. A nice insight in the nurse shark world. Be very proud of yourself. Really gutted to hear you missed that opportunity in the Barharmas. That would have been a spectacular trip for you.
I really appreciate your work with the channel and enjoy your content very much.
👊🏻🦈
Thanks Stephen, I’m sure I’ll be able to get out there at some point soon!
Congrats on the paper!
Well done to you and your team!
Nurse sharks: the Class Clown of the Ocean hahaha. Love you paper also!! I love to read and learn more about these sharks!!
It sounds really interesting to me. Is there an aquarium with Nurse Sharks that you can use to try out the walking hypothesis ? Maybe put them in water too shallow to swim in and see if they can walk to the deeper water or some food ?
This is great, I used to think that sharks in general have a similar behavior, but thanks to Sharkbytes I know that almost every shark is unique and distinctive, and now with this video I like nurse sharks even more.
I don't know why I haven't watched it until now.
Glad you have now and glad you enjoyed it!
the upside-down feeding doesn't cause tonic immobility? dose it only effect certain species?
I suppose it also needs stimulation of the ampullae of lorenzini at the end of the snout as well
This was very interesting and informative. Thank you for sharing your research and doing it in an easy to understand way for a lay person. Glad i found your channel. I'm looking forward to hearing about more of your research in the future. ^_^
It was a fascinating read
Thank you!!
This is fascinating research, thank you for sharing. Many animals adapt ways of using their limbs to suit their environments, so why not sharks.
Absolutely Misty, so glad we could share this with the world!
I've seen bottom-feeding catfish (plecos) using their fins to position themselves like this when they're feeding if they can't sit flat to rasp on their food. I have a 40 cm / 1 kg pleco as a pet right now and he does all sorts of shenanigans to eat his dinner or slurp on his bits of driftwood (xylivores gonna xylivore)... so this feeding behaviour from the nurse sharks looked totally familiar. Just like my boy Edgar when I give him some courgette.
Including feeding upside down like a right goofball.
I’ve seen a nurse shark in San Diego, CA & in the FL Keys in the wild😊 I’ve seen them in aquariums at home in NJ🥴😂
Next time you see one - keep an eye out for these behaviours!
This is a big reason I was drawn in by the channel. I really love hearing research findings when they're delivered in such an honest way. You are very engaging, even when you get into the "boring details." I think it's an awesome way to keep people listening and engaged.
That and waiting for you to make wonderfully bad shark movie bingo cards and discovering the SyFy shark movies catalogue. 😂😂😂
So glad you're enjoying the channel, thanks so much for your kind words!
Nurse sharks are awesome! I'm from Miami so the nurse shark was the first ever shark I saw in the wild since they're pretty common down here of course. Learning about them and their "walk" is so cool and the pov of the video is awesome too. And sidenote I love how the baited underwater cameras get abbreviated as BRUV lol.
CONGRATS for getting published. 🤍🦈🤍 What impressed me the most was your description of the nurse sharks pectoral fins!
One question that has nothing to do with sharks. Is the orange lamp a Himalayan salt dispenser? I've read that it can help with congested nasal passages amongst other functions. I so want to get one for myself.
Excellent episode Kristian!
Yes it’s a Himalayan salt lamp! Fortunately I don’t get many allergies, so I can’t speak first hand but I have heard they’re good for that. I just enjoy the soft lighting, especially in these darker months
Might I suggest trying setting crab traps disguised in corals, set with a tied crustation of some kind, and see if nurse sharks are still performing the same movements? Could also set up "puzzles" similar to what they do with dogs or cats (obviously more simplified and designed for underwater settings) in a research lab. This minimizes impact and influence from other marine animals
Overall, congrats on this achievement and well done
Also right before watching this I came across a UA-cam short by The Sun about a shark encounter with a kayaker. How do I send it to you?
All interesting ideas here, lots of scope for future research! R.e sending me links, you can always try on twitter (@kjparton) or Instagram (@mrkaijai)
CONGRATULATIONS 👏🏻 🦈💙
I LOVE this Video 😍
The Footage is AMAZING and the Nurse Sharks are STUNNING!! I always find myself wishing that they weren’t so viscous so we could interact with them Safely - where THEY Feel Safe and Comfortable and we feel the same way… but I’m not STOOPID LOL
I loved the upside down foraging as well as the using their Pectorals to help position themselves - their Incredible Intelligence is so Intriguing to watch 💙🦈🩵😍💙
Fantastic Work 🙏🏼
Do you think they can use their fins to hold food down kinda like how we use our palms to push things down??
Perhaps, it would be interesting to see if they did this. Although I think generally they rely on their powerful suction mouths to just engulf their prey very quickly!
@@SHARKBYTES thank you for always answering questions even though I'm sure mine was a pretty stupid one now that I think about it🤣
@@punk24 no such thing as a stupid question! Always ask 😁
Idk if I’m too late but I think I do have some further hypothesis
Is it possible that the sharks are trying to experiment where they could suck the food out of the bruv? They would be more familiar with more complex prey like crustaceans who might have some weaker spots than others or some fish with defensive spines that they might have to find a way to get around so they evolve to try foraging from different angles not just bc of the rock shape which isn’t present in the bruv case but also the preys anatomy. It might also be a more intelligent form of trial and error as well with them trying to see which area of the bruv have holes they can suck the food out of
Scence is science, well done.
Very very interesting. I enjoyed this. Keep up the hard work, loving the shark content 😁
Interesting, Kris😄, thanks for sharing. How do you decide who does what when you have a number of different co-authors? And do things ever get a little feisty when you disagree on stuff?🤨
I took the lead on this one because it was me who was reviewing the footage. Others work to their skills, some authors focus on stats, others focus on specific aspects of the manuscript (there’s a big section on the fin morphology written by a co-author because that’s his speciality). There’s generally no major feistiness, until it goes to review at the journal. Then it gets a little tense with the anonymous reviewers!
@@SHARKBYTES Cool, thanks for the explanation, buddy 👏😀
Fantastic work!
This is really interesting. I presume that shark behaviour is different in public aquariums as they are fed by hand or target more.
I do wonder if captive nurse sharks are "lazier" then wild nurse sharks. I know at the deep , tilly used to always be in the same area everytime. Unfortunately they lost tilly not long after they introduced Timothy, he stays in a different spot (he is in the shark tunnel cave). They did find that tilly had eggs when they found her, unfortunately she died over night. (She was my daughters favourite).
I’d imagine they may be a little lazier, although aquariums can definite provide some insight into behaviour for sure!
The sea puppies pawing at the treat bag.
Awesome, I have only seen them in a Aquarium
After binge watching your videos, I'm wondering whether Nurse sharks are immune to tonic immobility, or whether tonic immobility isn't produced when a shark goes upside down by itself. I'll have to read your paper.
Thank you for the interesting videos, and explaining things in layman's terms.
I had a strange encounter with a very large nurse shark on Cat Island. Bahamas. I was snorkeling in 10 - 15 ft and a nurse shark surprised me swimming up from behind and bumping me in the chest and continuing past me. It was 6ft+. I have never seen such a large nurse shark before. It later returned and bumped me again. We were staying on the beach where this occurred and snorkeled many times in this same area.Always mid day. It behaved in what I considered an aggressive manner if encountered. I never approached and always gave it its space. It seemed to have a thing for me. It never bothered my husband. This occurred in Shanna's Cove. Funny you mention Cat Island in another video.
Kristian, highly fascinating. Darwinian, pectoral fin walking into the future? Congratulations on your achievement, your hard-working contribution & for sharing ( sharking it) with us! Cheers!
Thanks Sheryl - so glad you enjoyed it
I love your channel and videos so much
It’s really inspiring
