Large Whipgoby
Bryaninops amplus
A fascinating goby that lives exclusively on gorgonian seawhips. The body is semi-transparent to reddish and usually blends well against the gorgonian host. The iris of the eye is red.
Morphology
A small, elongate fish with a relatively large, dorsoventrally flattened head and big eyes. Like other commensal gobies, this species posseses pelvic fins that are fused together into a cup-like strucutre which aids in clinging onto the host seawhip in strong currents. The maximum length is about 5 cm.

Bryaninops is a genus containing 16 currently recognised species. It belongs to the family Gobiidae, the most diverse group of fishes on the planet with over 1800 species.
