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.
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 ...
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 ... Tentacles are retractable limbs used to target and latch onto ...
A cuttlefish with W-shaped pupils which may help them discern colors. All octopuses [25] and most cephalopods [26] [27] are considered to be color blind. Coleoid cephalopods (octopus, squid, cuttlefish) have a single photoreceptor type and lack the ability to determine color by comparing detected photon intensity across multiple spectral channels.
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 ...
They contain only one set of gills. This cuttlefish can be recognized by its small body, slender tentacles, and lanceolate, or leaf-like, shape. [11] There are some characteristic differences between male and female trident cuttlefish, especially in their arms. For males, one set of their arms are significantly shorter than the others.
Tentacles are the major limbs used by squid for defense and hunting. They are often confused with arms —octopuses have eight arms, while squids and cuttlefish have eight arms and two tentacles. These tentacles are generally longer than arms and typically have suckers only on their ends instead of along the entire length.
