Description
The deepbody bitterling is a cyprinid bitterling endemic to central and southern Japan. It grows to about 8 cm and has a deep, laterally compressed body characteristic of the group. Like all bitterlings it reproduces with the help of freshwater mussels: using an ovipositor the female lays her eggs inside a living mussel, where the larvae grow up protected. The fish lives in slow-flowing and still fresh water in lowland habitats. Owing to habitat loss and the decline of mussel populations, the species is listed as Endangered (EN) on the IUCN Red List.
