Background: Octopus vulgaris is a common marine animal that can be found in nearly all tropical and semitropical waters around the world. It is a peaceful sea dweller with a parrotlike beak, and its primary defense is to hide through camouflaging adjustments. Bites from animals of the class Cephalopoda are very rare.
