Gymnapogon

Gymnapogon is a genus of fish in the family Apogonidae. They are native to the Indo-West Pacific and central Pacific Oceans, where they occur in reefs and nearby habitat types.[2] These species are usually no more than 5 centimeters long and have semitransparent bodies without scales.[2] The genus name is a compound noun formed by combining the Greek gymnos meaning "naked", referring to the lack of scales in the type species, Gymnapogon japonicus, and Apogon, the type genus of the Apogonidae.[3] One species, the B-spot cardinalfish (Gymnapogon urospilotus), is notable for its larvae being rather large, conspicuous and fast-swimming.[4]
