Introduction

The Cocos Frillgoby is a small fish that superficially resembles a number of similar goby species.

Identification

Fishes in the genera Bathygobius can be easily confused with those of Istigobius. The main difference is the overhanging snout in Istigobius. Bathygobius has larger elongate dark spots on the midside and numerous small white spots (Istigobius has white lines, but no spots). Istigobius tends to have brighter colours, with Bathygobius being black, brown and white.

Habitat

The species can be found in a range of bethic habitats from coral reef to rocky reef.
