Шаблон:Taxobox

Idiomysis is a genus of small mysids found in warm, shallow waters of Indian Ocean (including Red Sea) and Pacific.[1]

Anatomy

Mysids from the genus Idiomysis are just few millimeters length; their cephalothorax is gibbous and robust whereas the abdomen is characteristically curled up behindШаблон:R.[2] When compared with other mysids, Idiomysis has short antennae, relatively big eyes and small, usually unarmed telsonШаблон:R, however a single species, I. diadema, possesses a pair of short terminal spinesШаблон:R.

Systematics

There are six species described so far in the genusШаблон:R:

Ecology

Idiomysis live in the small groups (called swarms) of 5 to more than 40 individuals, which hover over sea bottom during a day and probably feed on the seafloor on the nighttime.[3] All known species are found in the shallow coastal waters, however they inhabit different niches and can be found on coral reefs, seaweeds, rocks or sandy bottomsШаблон:R. Two species – I. inermis and I. tsurnamali – are known for commensal relationship with the sea anemonesШаблон:R, whereas I. diadema is associated with the sea urchin DiademaШаблон:R. There are also reports of Idiomysis hovering above upside-down jellyfish, CassiopeaШаблон:R. Possibly mysids gain protection and/or food supply from this relationship, however the exact nature of the relation has not been studiedШаблон:R.

Distribution

The described species are known from Red Sea (I. diadema and I. tsurnamali), Mozambique Channel (I. mozambica), Gulf of Mannar (I. inermis), western coast of Australia (I. inermis), East China Sea (I. japonica) and western coast of South Africa (I. robusta)Шаблон:R.
