Bodotriidae is a family of

crustacean Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group ...

Cumacea Cumacea is an order of small marine crustaceans of the superorder Peracarida, occasionally called hooded shrimp or comma shrimp. Their unique appearance and uniform body plan makes them easy to distinguish from other crustaceans. They live in so ...

. Bodotriids have a worldwide distribution in shallow and deep waters. There are over 380 described species in over 30 genera, being the most diverse cumacean family. Their external morphology differs from other cumaceans by a combination of traits that independently are not unique to the family: the

is fused to the last abdominal segment (last pleonite), the dorsal part of the mandible has a boat shape (naviculoid), exopods exist on the third maxilliped and the first peraeopod, and there is a uropodal endopod with one or two articles.

Anatomy

In both sexes the telson is fused with the last segment of the pleon, forming a "pleotelson". Males generally have five pairs of

Diversity

Bodotriidae is divided into three subfamilies (Bodotriinae, Mancocumatinae, and Vaunthompsoniinae), although it has been suggested that Mancocumatinae belong to the Vaunthompsoniinae: ;Bodotriinae Scott, 1901 *'' Alticuma'' Day, 1978 *'' Apocuma'' Jones, 1973 *'' Atlantocuma'' Bacescu & Muradian, 1974 *'' Austrocuma'' Day, 1978 *'' Bacescuma'' Petrescu, 1998 *'' Bodotria'' Goodsir, 1843 *''
