Idiosepiidae, also known as the pygmy squids, is a family of squids in the superorder Decapodiformes.[1][2] They are the smallest known squids.[2]

It is the only family in the monotypic order Idiosepida[3] and the monotypic superfamily Idiosepioidea.[4] Phylogenomic analyses have shown that species in the family Idiosepiidae are sister to all other Decapodiformes.[5]

Description

Idiosepiidae are the smallest known squids: males can grow to about Шаблон:Convert and females to about Шаблон:Convert in mantle length. The mantle is elongate, obovate to cigar-shaped, with its posterior margin bluntly pointed at the distal tip. Their internal chitinous shell is vestigial, and the dorsal surface of the mantle has a unique oval adhesive organ, which secretes a sticky substance and is used to attach itself to seaweed or seagrass blades.[6] The head is prominent while the arms are short. In males, both ventral arms are differentiated, but they are also different from each other.[2]

Distribution and ecology

Idiosepiidae have an Indo-west Pacific distribution, from South Africa in the west to Japan and Russia in the east. They appear to be short-lived. They generally live in shallow water among seagrass and mangroves. They often adhere themselves to substrate, enabling camouflage and concealment during the day. They appear to be sit-and-wait predators. They are solitary. Mating is promiscuous with multiple matings. Young individuals are planktonic.[2]

Genera

The following genera are recognised in the family Idiosepiidae:[1]
