Open encyclopedia reference

Paedogobius kimurai is a species of goby from the subfamily Gobionellinae, and the only member of the monotypic genus Paedogobius. It is native to marine and brackish waters of inner bays in Japan, Thailand and Australia. Its English language common names include wide-gape paedomorphic goby and babyface goby. Its Japanese language common name is shirasukiba-haze. This fish is a protogynous hermaphrodite, undergoing a form of sequential hermaphroditism in which females change sex to male. It is a diandric species, one in which there are two types of male, the primary male that is born male, and the secondary male that is born female but later becomes male. The species is also paedomorphic, with mature adults retaining some characteristics of larvae. The genus name Paedogobius is inspired by this trait. The adult female lacks a pelvic fin. The adult female and both types of male generally measure between 1.1 and 1.2 cm (0.43 and 0.47 in) long. The fish is elongated and compressed in shape. It has a rodlike pelvis, with left and right halves not connected.
