A common gene between cuttlefish and almost all other cephalopods allows them to produce venom, excreting it through their beak to help kill their prey. [34] Additionally, the muscles of the flamboyant cuttlefish ( Metasepia pfefferi ) contain a highly toxic, unidentified compound [ 2 ] as lethal as the venom of fellow cephalopod, the blue ...
The cuttlebone of a cuttlefish. This is the largest hard part of a cuttlefish, maintaining the rigidity of its body.. The common cuttlefish is one of the largest species of cuttlefish with a mantle length reaching up to 45 cm and a mass of 4 kg on a presumed male, although this is for an exceptional specimen in temperate waters; specimens in subtropical waters rarely surpass a mantle length of ...
In female cuttlefish, the suckers on two pairs of arms are in rows of four. Then on the other pair of arms, the suckers are in rows of four only on the distal third of the arms. Additionally, the area that surrounds the cuttlefish's beak, called the buccal membrane, is covered with longitudinal ridges. [12]
The giant cuttlefish (Sepia apama), also known as the Australian giant cuttlefish, [3] is the world's largest cuttlefish species, growing to 50 cm (20 in) in mantle length and up to 100 cm (39 in) in total length (total length meaning the whole length of the body including outstretched tentacles). They can weigh over 10.5 kg (23 lb).
Sepia mestus is commonly referred to as the red cuttlefish. When undisturbed it is typically recognized by its red colouration and two dark spots on the posterior of the animal.

Cuttlebone, also known as cuttlefish bone, is a hard, brittle internal structure (an internal shell) found in all members of the family Sepiidae, commonly known as cuttlefish, within the cephalopods. In other cephalopod families it is called a gladius .
Sepia is a genus of cuttlefish in the family Sepiidae encompassing some of the best known and most common species. The cuttlebone is ellipsoid in shape. The name of the genus is the Latinised form of the Ancient Greek σηπία ( sēpía ) "cuttlefish".
