Futuna's Emperor

Akihito futuna

Declining

Overview

Akihito futuna, the Futuna's emperor, is a species of fish in the family Oxudercidae, the gobies. It is endemic to the island of Futuna in Vanuatu, where it inhabits the many streams present there. Males of this species can reach a length of 6 centimetres (2.4 in) SL, while females can reach 2.9 centimetres (1.1 in) SL.

Akihito futuna faces severe threats from its extremely restricted range on Futuna Island, making it vulnerable to any environmental disturbance. The species is threatened by habitat degradation from human activities including agriculture and coastal development. Its small population size and limited distribution create high extinction risk from stochastic events such as cyclones or disease outbreaks.
