Bryaninops loki (Loki whip goby)


Bryaninops loki is a small, elongated whip goby. It has a red to brown lower body, but color can vary depending on its host gorgonian. It is very similar to B. amplus, but a little smaller and a darker spot on the tail base. There is also a variation with a red to brown lower body and white bars. It is assumed the white bars are associated with guarding eggs or mating behavior.


This species is unassessed by the IUCN Red list, but considered a common species of whip goby. Probably often misidentified.

Reported from the Chagos Archipelago in the Indian Ocean, but assumed to live in other locations as well. Reports from the Red Sea, Egypt and Sudan as well. Known to live only on sea whips and gorgonian corals. Occurs usually with Junceela fragilis corals, Ellisella and Subergorgia species,  in a depth range of 6-45 meters.
