About this species
Exyrias akihito is a species of marine goby. Since the recent description of this species it has been found to have a wide distribution in the western Pacific including the Great Barrier Reef, New Guinea, Indonesia, the Philippines and the Yaeyama Islands, Japan. One individual was photographed in Palau, and on January 13, 2005, one was caught in the lagoon of Majuro Atoll in the Marshall Islands. This animal had only 9 soft rays in its dorsal fin instead of the normal 10, a congenital abnormality known to occasionally occur in gobies and other fish.
