It grows to 12 centimetres (5 inches) in length. 

It is native to eastern Atlantic Ocean waters, from Scotland in the United Kingdom to Senegal in west Africa. It prefers the temperate, coastal areas in shallow reefs and lagoons with rocky sea bottoms. 

The Rock Goby eats small crabs, larvae, and small fish. 

It makes a nest in rocky areas near seaweed. 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.
