Cuttlefish also have one of the largest brain-to-body size ratios of all invertebrates. [2] The Greco-Roman world valued the cuttlefish as a source of the unique brown pigment the creature releases from its siphon when it is alarmed. The word for the cuttlefish in both Greek and Latin, sepia, now refers to the reddish-brown color sepia in English.
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 ...
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] Overall, the female trident cuttlefish is generally larger than the male. [5]
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).
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 .
One of the largest beaks ever recorded was on a 495-kilogram (1,091 lb) colossal squid. The beak had a lower rostral length of 42.5 millimeters ( 1 + 11 ⁄ 16 in). Many beaks have also been discovered in the stomachs of sperm whales , as the stomach juices dissolve the soft flesh of the squid, leaving the hard beaks behind.

Sepia esculenta, the golden cuttlefish, is a cuttlefish ranging from the Russian seas to the Philippines and throughout the western Pacific. [1] This species of cuttlefish is a nektobenthic organism living with a range of depths between 10m-150m (33 ft-492 ft) [2] but is primarily found within the shallow, coastal waters from Japan to the Philippines at a depth between 10m-100m.
