"To undo your injuries, how many non-living food particles did you consume?!" "I don't know, how many loaves of bread have you eaten in your lifetime?"
If you listen to the voice-over all the way through, you'll hear that the vampire squid mostly eats mucous from animals that is falling through the water column. They are not aggressive or dangerous to much but very small animals that live in the deep midwater environment.
Leon Lionheart Just eats detritus. No filter required. Filter feeders suck in water and keep the solid parts, while this thing just grabs the solid parts.
The vampire squid's scientific name is Vampyroteuthis infernalis, which can be translated from latin to vampire squid from hell. Drawings from the original description (Chun, 1903) show the animal in black with red eyes, which is perhaps why the scientist thought it looked like a vampire. Keep in mind that they were looking at dead specimens from a net trawl back then, but in this video, we show live animals in their natural habitat.
The vampire squid would likely flash its photophores (light organs) and take a defensive posture if disturbed. It is unlikely that they would attack anything larger than a small crustacean.
Scrolling through the comments I had a little rant about how all of you called the Vampire Squid "ugly" or saying to "kill it". And that's not right because if you were ugly (no offense) people might say those things if your a mean person or whatever. So how would that make you feel? Or if you were that squid in the video (let's just be realistic) it wouldn't happen but what if you saw these comments? Yea I'm really outraged by this and you people should be really ashamed of yourselves. The Vampire Squid isn't weird,or gross or ugly. It's BEAUTIFUL.
Yes, the organic detritus would not seem to be particularly nutritious. However vampire squids complement their frugal diet with an extremely energy-efficient lifestyle and unique adaptations. Hoving explains "Because of its unique adaptations, the vampire squid is able to permanently and successfully inhabit the center of the oxygen minimum zone, an otherwise hostile environment where the vampire squid's predators are few, and its food is abundant."
I was always the weirdo of people when it came to picking favorite animals. When people asked me what was my favorite squid or octopus (or cephalopod, pretty much) I said this one. They though I made that up the second they had asked me it lol.
Its beautiful and totally unique and its perfect to just drifting and dancing not bothering nothing but if you mess with it you will get a big scare lol.
At first I was terrified looking at this, but it's an unbelievable squid wow great video, there are so many sea creatures and still so many undiscovered!

I wonder: Why does this videos always star a bored voice? I mean, if this is what you love as a Marine biologist shouldn't you be hyped as fuck for this amazing finding? Same goes for Discovery and Nat-Gio documentals. Share your hype!
I'm pretty certain this gentleman is pretty happy with his line of work. Perhaps what we consider 'excitement' in the tone of voice for some people would be excessive for others. Either way, I'm content with the delivery
That is a little jellyfish swimming on the left. It is a narcomedusa called Aegina sp. You can see an image of it here www.mbari.org/news/homepage/2006/newspp.html (5 photo from the top). You can also read more about this abundant jelly here jellieszone.com/aegina.htm
Dumb question: they lack the feeding arms of squid, yet they have these two feeding filaments-are the structures analogous? Otherwise to what would these structures be analogous?
The primitive configuration of coleoid cephalopods is with 10 equal arms. Modern decapods (squid) with 10 unequal arms can be logically traced back to the earlier form. Octopods, with eight arms, have apparently lost one pair." The vamp's filaments are most likely homologous to the second pair of arms in the 10-armed primitive cephalopods. The squid's feeding tentacles are also probably derived from the second pair of primitive arms; but the filaments and tentacles probably aren't homologous because they appear to have evolved separately.
+Monterey Bay Aquarium Research Institute (MBARI) If they are derived from the same pair of primitive cephalopod arms, wouldn't that make them homologous to each other?
+Lew South From Young, R. E. (1967): The axial filament nerves of Vampyroteuthis infernalis are joined to two separate parts of the brain. One branch of the nerve, apparently efferent, arises from the anterior portion of the middle subesophageal mass, and the other, apparently afferent. enters the ventral magnocellular lobe. Since this innervation is entirely different from that of the arms, the filaments can no longer be considered homologous with the arms. The validity and primitive nature of the order Vampyromorpha, therefore, needs to be reexamined. science.sciencemag.org/content/156/3782/1633 From Hoving and Robison (2012): "Both ROV observations and laboratory experiments led to the conclusion that vampire squid use their retractile filaments for the capture of food, supporting the hypothesis that the filaments are homologous to cephalopod arms. Vampyroteuthis' feeding behaviour is unlike any other cephalopod, and reveals a unique adaptation that allows these animals to spend most of their life at depths where oxygen concentrations are very low, but where predators are few and typical cephalopod food is scarce." Scientists aren't in agreement as to the homology of the filaments.
The vampire squid is rather small, reaching a maximum of 13 cm mantle length. The mantle is all that is visible behind the head: the outer body wall and the fins are all part of the mantle.
I'm totally flabbergasted. This video is 10 years old, and I know these squid, yet hadn't bothered reading anything about it. I knew it was abyssal and a bioluminescent, that's all. But I had no idea it was a detritivore and that it lived in this particular biotope. Awesome, both the squid and the biotope itself.
Somewhere in the universe in a watery expanse on some planet or moon, something similar to these probably exist. May even be five billion years older than us. Maybe they rule some quadrant of the galaxy! :O
yeah that makes sense, just how there is little oxygen and manages to live. What if certain animals feed on certain gases, or pressures. That would be some crazy looking creatures, honestly.
I love his eyes their so big and blue lol like i wanna poke it and it will go back inside its body or something not trying to sound mean he just looks cute its like he has 2 sides the red side is his cute side and the spike side is his angry side
My daughter knows so much about sea creatures from the Octonauts :) She's 4. The other day she identified a damsel fish in a magazine and a giant syphonophore!! I was very proud. Actually, she saw the episode with the Humuhumunuunukuapwa'ah before I did and she mentioned it to me and I was like, the what? _Humuhumunukunukuapua'ah._ Did you make that up? _No._ She was right. There it was. Octonauts and the humuhumunukunukuapua'ah. Lol. Awesome.
MagcargoMan Lol. Sorry, I was being lazy that day and spelled it phonetically as best I could. I don't think I did too badly :) Anyway, here's some details to help you find it: _The reef, rectangular, or wedge-tail triggerfish, also known by its Hawaiian name, humuhumunukunukuāpuaʻa, also spelled Humuhumunukunukuapua'a or just humuhumu for short (Wikipedia)_ _Scientific name: Rhinecanthus rectangulus_ _Higher classification: Rhinecanthus_ _Rank: Species_ _Symbol of: Hawaii_ Your comment made my day it was so silly. I get a feeling you're just flat out teasing me anyway :)
Actually, this is just the censored version for the public, you know, like the Anne Frank diary you learn about in school. In reality, they feed on your dreams.
