Cuttlefish are marine animals of the order Sepiida. They belong to the class Cephalopoda (which also includes squid, octopuses, andnautiluses). Despite their name, cuttlefish are not fish but molluscs. Recent studies indicate that cuttlefish are among the most intelligentinvertebrates.[1] Cuttlefish also have one of the largest brain-to-body size ratios of all invertebrates.[1]
The origin of the word cuttlefish can be found in the old English term cudele, which derived in the 15th century from the Norwegian koddi(cushion, testicle) and the Middle German kudel (pouch), a good description of the cephalopod’s shape. The Greco-Roman world valued the cephalopod as a source of the unique brown pigment that the creature releases from its siphon when it is alarmed. The word for it in Greek and Latin, sepia (later seppia in Italian), is used to refer to a brown pigment in English.
Cuttlefish have an internal shell (the cuttlebone), large W-shaped pupils, and eight arms and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from 15 cm (5.9 in) to 25 cm (9.8 in), with the largest species, Sepia apama, reaching 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in weight.[2]
Cuttlefish eat small molluscs, crabs, shrimp, fish, octopuses, worms, and other cuttlefish. Their predators include dolphins, sharks, fish, sealsand other cuttlefish. Their life expectancy is about one to two years.
