Description
The green goby is a small goby of the family Gobiidae from the western Atlantic off the east coast of North America. The species grows to about 6 cm and has a slender, translucent body with a greenish sheen. It inhabits estuaries with fine silt-mud bottoms and is known as a sponge-dwelling goby: it lives in close association with sponges, such as the red boring sponge (Microciona prolifera), in which it finds shelter. As a small bottom dweller it feeds on small zooplankton and small invertebrates. Gobies cling to the substrate with their fused pelvic fins. Owing to its small size the species has no fishery value and is harmless to humans.
