Description

Acheilognathus typus is a bitterling (family Cyprinidae) native to Japan. The species reaches about 10 cm and has a deep, laterally compressed, silvery body; spawning males develop brighter colours. It lives in slow-flowing rivers, ditches and ponds in a temperate climate. Its reproduction is distinctive: the female uses a long ovipositor to lay eggs inside living freshwater mussels, where the young grow until they can swim. Its diet consists of algae, detritus and small invertebrates. The species is considered Vulnerable (VU) owing to the decline of suitable habitat and host mussels.
