Description

The dusky brotula is a small, live-bearing brotula from the western Atlantic and Caribbean. The species grows to about 10 cm and has an elongate, dark-brown body with long, continuous dorsal and anal fins. As a shy, secretive fish it keeps to crevices, undersea caves and cavities of reef and rocky shore, between about 6 and 70 metres, where it hunts small crustaceans at night. Unlike many fish it bears live young. The fish is harmless to humans. The IUCN has not evaluated the species.
