Yellow Coralgoby, Gobiodon okinawae Sawada, Arai & Abe 1972

More Info


Distribution

Offshore reefs of north Western Australia, and Ashmore Reef in the Timor Sea, to North Solitary Island, New South Wales: also Cocos (Keeling) Islands and Christmas Island in the eastern Indian Ocean, and Lord Howe Island in the Tasman Sea. Elsewhere the species occurs in the tropical, Indo-west-central Pacific.
Inhabits reef lagoons, living in association with tabular Acropora corals throughout its range. Individuals shelter among the branches, and may also hover just above the coral.

Feeding

Biology

A hermaphrodite capable of bi-directional sex change in which adults have the capacity to shift between male and female function.

Similar Species

The Yellow Coralgoby, differs from the similar and sympatric Howson’s Coralgoby, Gobiodon howsoni, in usually having 13 vs 15 branched caudal rays, two vs one enlarged canines on the posterior dentary, the genital papilla falling well short of the anal fin, vs usually reaching the anal-fin origin, and having a uniform bright yellow colour vs 1-2 brown stripes on the body in G. howsoni.
