Class: Cephalopoda
Order: Octopoda
Suborder: Incirrina
Family: Octopodidae
Subfamily: Octopodinae
Species: Octopus vulgaris, the Common Octopus.

Members of the class cephalopoda are carnivorous hunters. They have the most advanced nervous system of all invertebrate animals and are an important example of advanced cognitive evolution in animals.

O. vulgaris is the most studied of all octopus species and possesses excellent eyesight, capable of distinguishing shapes, textures, and colour. It is the only animal which has been conclusively shown to use tools, and is proficient at learning simple processes such as unscrewing a jar.

Cephalopods are able to release dark pigment into the water as an escape mechanism, which in the past has been extracted and used by humans as an ink or dye. The word sepia comes from the Latin word for cuttlefish, s?pía.

Cthulhu's head with a pair of tattered wings behind while the tentacles loop below it. Update: I had to thicken a spot on the wings even though it's printed just fine before.
