Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from 15 to 25 cm (6 to 10 in), with the largest species , the giant cuttlefish ( Sepia apama ), reaching 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in mass.
Certain squid species possess a tail, which is an extension of the body past the fins. [5] The tail may be said to start at "the point where a hypothetical line, continuous with the broad posterior edge of the fin, crosses the midline of the body". [ 1 ]
The inner surface of the suckers (acetabulum) are reinforced with rigid sucker rings which are smooth in Sepiolida, have blunt teeth in Sepiida and sharply pointed teeth in Loliginidae and Oegopsida. The arms and/or tentacles of some oegopsid families have also evolved claw-like hooks.
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 ...
They are further differentiated by having a rigid body supported by a cuttlebone; this mantle is distinct, whereas in octopuses the head and mantle surface have fused together. 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 ...
The broadclub cuttlefish is the second largest cuttlefish species after Sepia apama, growing to 50 cm (20 in) in mantle length and 10 kg (22 lb) in weight. [7] Like many cephalopods, the broadclub can be seen displaying a range of colors and textures. Commonly they are light brown or yellowish with white mottled markings.
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".
Sepia trygonina, the trident cuttlefish, is a species of cuttlefish in the genus Sepia from the Red Sea and the western Indian Ocean. [4] They are also a major source of food for larger marine life like dolphins, seals, and even birds.
