Description
The red clingfish is a tiny bottom fish of the clingfish family (Gobiesocidae) from the western Atlantic and Caribbean. The species grows to only about 3.5 cm and has a scaleless, red-brown body with a sucker on the belly, formed by the modified pelvic fins. It lives in close association with sea urchins of the genus Echinometra, mainly for protection, sheltering among the spines. With the sucker it clings firmly to the substrate. It feeds on tiny invertebrates. Owing to its small size the species has no fishery value and is harmless to humans.
