Subfamilies[1]

Cylindroleberididae is a family of ostracods that shows remarkable morphological diversity. The defining feature is the possession of gills: 7–8 leaf-like pairs at the posterior of the body. Other features common to all species in the family include a "baleen-comb" on both the maxilla and the fifth limb, a sword-shaped coxal endite on the mandible, and the triaenid bristles on the basal endites of the mandible.[2]

Species of the Cylindroleberididae are found in marine areas, from shallow waters to depths of more than 4,500 metres (14,800 ft).[3] Most species are approximately 2 millimetres (0.08 in) long. In 2006, there were 219 described species.[4]

A fossil discovered in 2003 with preserved soft parts has been assigned to the Cylindroleberididae.[5] The fossil appears to have gills and is thought to date from 425 million years ago.[5]
