Vampire Squid: I’m no vampire, and I’m not even a squid!
My scientific name is Vampyroteuthis infernalis, which translates to “vampire squid from hell.” Too bad I’m not actually a squid or even an octopus, even though I have characteristics of both. I’m not a vampire either as I don’t suck blood! I do have a vampire-like cloak that I can wrap myself in (see MBARI video, it’s really cool!). As for being from hell, I dare you to live in pitch black darkness at 2000 feet deep (610m) 24/7 and not consider it hell! Just kidding, I am perfectly adapted to life in the deep sea, as my species has been around for millions of years. I am still a cephalopod, a group that includes octopuses, (true) squid, cuttlefish, and nautiluses.
I have been in the news lately because a study found that I eat feces and corpses. They are some of the components of marine snow, the organic bits and pieces that drift down from the surface to the bottom of the ocean. Maybe humans would not eat those things, but food is scarce in the deep sea. I’m constantly on the move, and I trap food in long, sticky, and retractable lines that I cast out from my body. My one inch (2.5cm) wide azure eyes are perfectly adapted for seeing in low, or no, light. I also have dark blue bioluminescent photophores (lights) all over my body. Bioluminescence (i.e. glow-in-the-dark light) is the only source of light in the deep sea.
So like octopuses I have 8 arms, but I don’t have ink sacs. Instead my “ink” is a mucus ball comprised of bioluminescent lights. It works for me when I feel threatened, and besides, black ink in the black deep sea wouldn’t do me much good.
I hope you can appreciate me now that you know I am more than just a feces eating scavenger, as I am one cool and wholly unique species!
