Vampire Squid (Sanctuary)

Vampire Squids are a nearly extinct species of abnormal squid from the TV series Sanctuary. They are called "vampire" not because they drink blood (they subsist on plankton) but because of their high intelligence. They have been known to create complex geometrical patterns on the ocean floor. They are normally very peaceful, so peaceful they are often killed by predators when young. They become very violent however in the presence of Southern-hemispheric sea scorpions.

Behind the scenes
In real life, the vampire squid is an animal which rarely grows more than a foot long, while their Sanctuary counterparts are as big as giant squid. They are so named because their arms have teeth instead of suckers.
