It grows to 18 centimetres (7 inches) in length. 

It is found in the Atlantic Ocean, the Mediterranean Sea, and the Black Sea. It prefers tropical reefs, lagoons, estuaries, and inshore waters with seagrass and algae.

It prefers muddy or sandy sea bottoms. It is benthic because it lives on the bottom of the ocean.

The Black Goby feeds on invertebrates and small fish. 

It makes a nest in rocky areas near seaweed and seagrass. The female lays up to 7,000 eggs under rocks and shells. The male guards the eggs until they hatch after about 19 days.

It lives, on average, for 10 years.
