Ok, I had NO idea that jellyfish reproduced like that. I've never heard of animals making babies that multiplied themselves. That is so cool and almost unbelievable! The photography in this video is beautiful! I love you deep look ❤
No this is different. They alternate reproduce via fertilization and cloning. Twins in humans are always created by fertilization, they still have two parents. There are lots of other animals and other organisms that do this though.
It’s kinda like an amalgamation of different beings: Ancient plants (think prehistoric ferns) also had two stages of development that are condensed into the same plant nowadays while there are e.g. salamanders and insects that can multiply asexually to increase population but also sexually to maintain genetic variety
Jellies seem so alien, especially with their reproductive tendencies (and even the ones that return to polyp after some time spent in adulthood), they're one of the coolest and most interesting sea creatures imo

Sea anemones are perfectly able to move about and even swim, after a fashion. Not well or quickly, but they can do it. They are like jellyfish who decided not to float free through the ocean.

It is really weird, a totally sessile animal just starts popping off other, completely different, free swimming animals. Its so weird how a body part just turns into its own organism.
@@speziell1575 I actually assume that they are like babies spawning out of "plants". And their parents are actually making "plants" for the sole purpose of making babies.
Imagine all the weird alien creatures that sci-fi authors have given us, and all the while, Earth goes: "Oh yeah? Those squishy things with stinging tentacles with no brain? Imagine an entire stack of clones that wiggle free one-by-one. Oh, and those came from clones too. :)"
I mean, we are not that much less weird. We are a pile of clones changin themselves to do difernt things that all work together to make a bigger mobile colony. If you look at our cell types it gets wild. Like with Macrophages that are pretty amoeba like and move indipendently around hunting for things not suposed to be there. Or our bones, that are in a way seperate from us, being a latice struture build inside our bodys by specialised cells and colonised by others that reinfoce this latice. Neuronal cells too, did you know that they too can freely move around, again quite amobea like, before they settle down and start to branch out?
@@theexchipmunkThe very fact that we are "mostly" (I believe) not-human is very mind-blowing. By percentage, I've heard that a minority of our cells/biomass is actually our own; the rest is actually just other species inside us. Like, "all your gut bacteria" and all that.
@@zenith9825 Yeah, and if I remember right, around 8% of our genome is made up of various species of bacteria that decided to have a symbiotic relationship with us _(e.g. gut bacteria)_
@@Khann_2102 Both are classified in the same phylum (Cnidarians). Anemones are classified in the class "Anthozoa" and the subclass "Hexacorallaria" (which also includes corals). Jellyfish are classified in the subphylum "Medusozoa" which contaims a few classes, the most common ones are "Hydrozoa" and "Scyzophozoa"
Even cloning upon cloning, only the smallest percentage will survive to adulthood. So to deal with predators either consistently be in large groups or good at dodging the ambushes. Man I would think with all those tentacles, they'll just bounce on their adversaries and jump like a jumping jellyfish.
Imagine growing up in a stack of undefined flesh that slowly resolves itself into a pile of babies, and each baby just peels off the mass and tumbles down the pile once it’s fully grown.
I am so glad you guys finally made a video about this! Ever since I learned about how jellyfish reproduce, I’ve shared it with as many friends as would listen. You guys get the best footage, and you explain things so clearly! I can’t wait to share this!
For the last time Jimmy, give me the remote! No? Okay, I didn't wanna say this but... you're a clone! Yes, you! And ever since you were a kid you've been... pancaked! That's right, you better leave. Here, let me help push you away!
The lifestyle of the sea jelly is so successful that these guys have been around for *millions* of years! Also, you forgot to mention that jellyfish polyps duplicate the same way coral polyps do! This makes sense considering the fact the two are also related.
A little trivia: A "factoid" is misinformation that has been spread by word of mouth for so long that it is commonly mistaken as fact. A couple examples being chewing gum staying in your stomach for seven years if swallowed, or that ostriches bury their heads in sand when threatened.
Ooh, I love jellyfish! Especially moon jellies. Ive never theough about how they reproduce, but this makes sense. This is a very unique and interesting way to reproduce. 10/10 episode, probably my favorite thus far!!
Great video. Seeing this 3:55, in your video made me see & understand how a sea turtle could easily mistake a plastic bag, for a jellyfish! No wonder it is such a problem! Those poor little adorable sea turtles!
Because of this video I finally understand the life cycle of jellyfish even though I had to learn about it 3 years ago and it only now clicked in my brain. This young biologist can finally let this subject rest, so THANK YOU. Now it’s just the life cycle of coral that has to click in my brain
I was in St. John snorkeling a couple years ago and I didn't realize it was a Jellyfish bloom. (The adults were mostly at or near the surface) and when I noticed finally, I freaked out and noped my way out of the water and back onto the boat.
One more amazing evidence of the "thin border" between the animal and plant kingdoms. Thank you, Deep Look, for reminding us once again that we are all one interconnected world. 🐚🐙🐋🐟🐠🐡🐬🐾🤍
Here in Venezuela there was recently a jellyfish bloom near the sea shores. Normally they don't come to the shores. It's believed to be caused by more contamination in the waters (because this species, the "cannonball" jellyfish, is mainly a filter feeder targeting algae), and a decrease in sea turtle population.
The fact that creatures without a brain or even nerve cells can do this is absolutely insane! I’m surprised nobody has thought of making something like this but the size of a elephant and on land and turn it into a horror movie or something. Would probably work pretty well.
sooo what are the actual numbers like? how many young could one mama jelly spawn? how many clones can a polyp make? how many ephyra per polyp? and why does this sound crazily exponential?
I usually saw on how Jellyfishes reproduce on books back in my elementary school days, but to here, it really does seemingly pretty cool than only the figures and one picture. Jellies were really are almost alien like creatures on earth
Amazing video! It really gives us the visuals to really see what's going on in the classic jellyfish life cycle that we've studied in high school or university :D Also how fitting that once the ephyrae break free, they resemble little sea snowflakes :)
They actually do: In fact, all jellyfish are poisonous and sting, however there are many species like the Moon Jelly whose toxins or stingers are not strong enough to harm humans so it goes by unnoticed. To plankton, they are very much a dangerous predator.
Here in Australia we have many cool species of jellyfish in the ocean. I recently went to the beach and found that hundreds of them had washed up on the shore. Massive jellyfish that were about the size of those mini basketballs that you'd have growing up. They were soft, slimy, and surprisingly dense in comparison to many others. Their surface had an amazing brain-like texture to it. It was cool to see! This video is perfect timing!

kind of happens to humans too, doesn't it? Albeit rarely. but some families have a disposition for getting identical twins

This jellyfish life cycle makes the story of the stork carrying a baby more wholesome.
This is a stork cloning itself so it could send another copy of itself into the sky while the 'real' stork stay on the nest
I've seen illustrations of this for years, but never saw a video of it until now. I am so very happy to have finally seen it.

I never really thought how jellyfish grow in numbers, it all makes sense now

Zefrank missed a good opportunity with this one!
What I'm interested in, is whether or not the leftover polyp bits return back to the polyp phase after all of the jellyfish are released.
Me too
I was wondering the same thing!
It seems to me like all the polyp ends becoming jellyfish.
Always love a new deep look video! Keep up the amazing content! And I love how a jellyfish was named Medusa. That’s awesome
Thank you! Will do!
That's actually the normal name of the jellyfish in Italian :)
And on top of it, there is a jellyfish species that's immortal, going through their life cycle over and over again
until eaten
@@shockal7269not if left alone.
@@melvacaoyona-ollosa278 left alone until eaten

Thanks again @AquariumOfTheBay !

We agree!
Almost 40 and it’s only now that I see a good video showing well the reproduction cycle of jellyfish. What a great channel!
Wow, thank you!
Nice! I've seen this plenty of times in images, but this is the first time I've seen a UA-cam documentary video actually showing it.
Wow, thanks!
I will call these baby jellies “Squishies” and they shall be mine and they shall be my Squishies.
Nemo Nemo Nemo
Then what will happen to the part that still clings to the rock? Does it break free too or just lay there and die?
This is like real life shape shifting with a twist

So how many babies do you want?
Jellyfish: yes
They look like-like something, but I can't put my finger on what.
Moral of the story is Jellyfish are plants.

Just stay in the ocean and I'll stay on the land. Deal?
I knew they cloned themselves, but didn't know about their second method of doing so! Lovely video
Thanks! 😃
They polyps remind me of hydras, they’re in the same family so I can see why.
Finally, some explanation of what polyps are.
🤯! Mind blown. Every. Single. Time.
shoutout for cameraman staying that long under the sea to capture the life cycle
You would be amazed at how long Josh can hold his breath.
I did learn about this in biology class but i had never actually watched it happen! Thanks for the video!
You are most welcome.
in a lot of ways, true jellyfish are like ferns where they have two adult stages, just that jelly polyps aren't haploid like fern gametophytes
Our next video on 4/16 will be about the fern lifecycle! And there will be gametophytes a-plenty.
