Vampyroteuthis infernalis



 also commonly called vampire squid are a nearly extinct species of abnormal squid.

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 live in burrows near coral reefs. 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.
