Description
The tusked goby is a tiny goby of the family Gobiidae from the western Atlantic and Caribbean. The species grows to only about 2.5 cm and lives in close association with large barrel sponges, where it hides in crevices along the outside and sometimes stays within the sponge. The reddish body is inconspicuous among the sponge tissue. As a small dweller it feeds on tiny invertebrates. The relationship with the sponge provides protection from predators. Owing to its small size the species has no fishery value and is harmless to humans.
