Grimalditeuthis bonplandi: A deep-sea squid with tentacle tips that "swim" on their own
Вставка

- Many deep-sea animals such as anglerfish use parts of their body as lures to attract prey. Some deep-sea squids may use this strategy as well. This video from MBARI's remotely operated vehicles (ROVs) shows a type of deep-sea squid that appears to use a different method to lure prey-its tentacle tips flap and flutter as if swimming on their own. Researchers hypothesize that the motion of these tentacle tips may induce small shrimp and other animals to approach within reach of the squid's arms.

This video was captured in 2005 with MBARI's ROV Tiburon, which at the time, only had an standard definition camera on it. This species is so rare, we have not observed another individual since we've upgraded our ROVs with high definition cameras.
The long feeding tentacle club manoeuvres the tentacles by undulation and flapping of the clubs’ trabecular protective membranes. These tentacle club movements resemble the movements of small marine organisms and suggest the possibility that this species uses mimicry by the tentacle clubs to lure prey.
The part at the tip of the head that you mentioned are two fin-like "floatation devices" (= secondary fins) which arise from tail. Very little is known about how they reproduce. In the research described here, they found parts from shrimp and other crustaceans as well as squid parts!
looks simaler to the sword tail squid
Yes, the long feeding tentacle club manoeuvres the tentacles by undulation and flapping of the clubs’ trabecular protective membranes. These tentacle club movements resemble the movements of small marine organisms and suggest
the possibility that this species uses mimicry by the tentacle clubs
to lure prey.
The second long tentacle is probably not deployed in this clip. In 25 years operating ROVs at MBARI, we have only observed this species once, so we were quite lucky to see this behavior!
@ETHAN SEBASTIAN LAYANA GAMARRA This is an adult.
That's so neat! It really does have a tentacle tip with its own tiny, little pair of swimmy wings. The deep ocean and all of it's creatures never cease to amaze me.
This video sequence was probably shot about 20 feet away, but the camera can zoom in and out. The larger individuals of this species are about 15 cm (~6 inches) mantle length. The mantle is the part just behind the head and eyes all the way to the tail and fins. As you can see in the video, the arms are at least as long as the mantle and the feeding tentacles can extend 2-3 times longer.
What a beautiful specimen.
Absolutely amazing!
great close up views of the squid
couple of species of Chiroteuthis and Asperoteuthis have similar kind of tentacle, so i assume they use the same strategy for hunting. Would like to see one soon. Wonderful video and good work!!!
The "lure" seems to imitate the figure and swimming characteristics of a tiny squid itself. Is this possible, or it's just my illusional and non expert eye?
No you're not seeing things you're right that's pretty much what it was doing. After all remember that more than one type of squid will use a wounded smaller squid as bait hell isn't that how they actually finally got a picture of a a giant squid? Considering all the other really wild adaptations that you see squid use like the magnapinna the colossal the Giant the strawberry squid I mean heck the list goes on and on then occasionally you have so many different adaptations that occasionally you run into one that's not even the squid! Look at the vampire squid the one thing that really caught my attention more than the lower though was was that an egg case that was carrying above the fence or what is it first it look like an egg case and then I couldn't tell what it was that's actually what I have a greater curiosity about because it seems like a second pair of fins
Incredible footage.
What I see quite interesting is the tip of the head with that shaggy comb that seems full of small zooxanthellae of some sort while the rest remains quite transparent; wish I could dissect that part. The stomach is empty and seeing it floating like that in the water column, I still wonder how can they actually catch anything bigger than a shrimp. And how they reproduce? They should congregate like normal squids but it seems unlikely as the individuals are sparse and seen alone just like that (?)
Interesting how it's inner organs look to be surrounded by water and water seems to flow in and out of it's body cavity.
Beautiful! ... check out: @ 2:25 mins and 3:08 - 3:19 mins
I would like it if these videos were longer. 5-6 minutes would be nice. Especially if there are extended close up views of the body and internal organs.
But thank you for all your videos of marine invertebrates. There's more than fish in the ocean, a lot more.
spoopy
its front looks a lot like a jellyfish. seems to have a similar way of moving too. just a thought.
but why at such a low resolution?
how far away are you from the squid cause it looks small from the distance. Or how big does this thing get exactly?
Again...You need someone to describe what we are seeing. Maybe you should edit this video and have a scientist talk about this gorgeous fish. Thank you for all of your videos...I love them. I do like the ones where the scientists are talking a little more though
Yep, looks like a lure to me too.
I'm not sure I understood what he did. Was the tentacle used as a fishing rod, or what?
so what function does this tentacle serve?
is it some sort of prey lure or is it a sensory organ?
evolution is too hard. i should just quit while im ahead
Could you give some info about how long this thing is?
Wonder if they will name it an Angler Squid?
Anyone have an idea of the scale of the squid?
Beautiful. Isn't it just using the anglerfish trick of luring in prey? It's got to serve some useful purpose, or it would've been weeded away M years ago. the benthic economy can't support anything that isn't useful to survival, even if we can't immediately understand how something is (even if it looks like all your fingers are dancing their own different ways).
The current theory is that it uses the wiggling like an anglerfish, yup. It either creates a wake in the water that attracts animals thinking it's prey, or stimulates bioluminescent plankton in the water column around it c:
incredible video. Any ideas as to the purpose of its unusual tail that extends beyond the usual two fins squids normally have?
It is a decoy, a trap for smaller fish
Mario Z. no it's not it's a rhizocephalan a parasitic barnacle normally found on crustaceans, but in the deep sea it has diversified beyond crustaceans to squids and even sharks
wouldn't it be possible for it to still function as a lure tho? im not familiar with the predators of rhizocephalan but is there a possibility that it might function as a symbiotic relationship where the squid provides safety and energy in trade for using it as a lure? :)
there are no records of rhizocephalans parasitizing mulluscs of any kind. They are highly specialized, extremely devolved parasites of other crustaceans. They are barnacles or were originally millions of years ago, but today only their larvae look similar to other barnacle larvae. The adults have lost all adult barnacle traits, and consist of an external reproductive organ that protrudes from the base of its host's tail that looks like a an oddly shaped lump of flesh protruding from the base of the crustaceans tail with rootlike tendrils extending throughout the crabs body to draw nourishment from its host at great expense. Considering how burdensome they are on their crustacean hosts, were one found that lived on a squid it no doubt would be just as onerous and do less than nothing to help its host survive. Nothing preys on the rhizo specifically. If it is eaten it is as a result of its host becoming prey to something else. Though it is the target of a hyperparasitic copepod that does the same thing to the rhizo the rhizo does to the crab. Unfortunately for the crab, its fate remains the same regardless of that happening.
thanks a lot :D
really?
Looks like a boss from Final Fantasy.
In my opinion it is elegant & beautiful...
That is one strange woomy
Anybody but me check their speakers for sound?
No sound
You know what I call those two big, beautiful eyes? A family resemblance. That's our distant cousin, you know. :)
In fact they evolved their eyes on their own, so they're not a sign of our common heritage. They are really distant cousins :)
@@hanumanlesinge4472 as a matter of fact, we;re not cousins at all! this is what scieitintist refer "squid" while you and me are a monkey species title "homo spaien". knowledge :)
@@hellishtimber Well strictly speaking, we're not cousin to most Homo sapiens, it's a figure of speech to talk about relatedness, and all life on earth is related more or less distantly through a common ancestor.
@@hanumanlesinge4472 oh wow!! so in many ways we're are squids -_- ...
weird....
Its beautiful
I read the research paper and enjoyed it! I like this guy because the Tully monster has a second tip finned tail too ! But the Yale paper was printed ONLY to get hits & views ! hint hint Yale's paper is false news ! Dr. Eugene S. Richardson jr. and I knew what the tully was all the way back in Oct. of 1973 ! Had we published then it might not of become the Illinois State fossil. Our most important research fossil is the one that is used by the State on their web sites . actual size is 12 inches Thank you
I keep thinking it says that and I have to do a double take every time I pass this vid in my history! @furonable
لا إله الا الله محمد رسول الله
its squid girl
amazing, and creepy
:55 DID IT JUST BLINK!?!?
