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.
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 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".

Cephalopod limbs bear numerous suckers along their ventral surface as in octopus, squid and cuttlefish arms and in clusters at the ends of the tentacles (if present), as in squid and cuttlefish. [9] Each sucker is usually circular and bowl-like and has two distinct parts: an outer shallow cavity called an infundibulum and a central hollow ...
Cuttlefish with two tentacles and eight arms. In zoology, a tentacle is a flexible, mobile, and elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work mainly like muscular hydrostats. Most forms of tentacles are ...
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.
The feeding tentacles are typically used to capture prey by rapid extension. [6] 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 ...
