Caribbean reef shark (Carcharhinus perezi). A remora fish (Echeneis naucrates) is seen attached to its lower jaw. The Caribbean reef shark is found in the tropical western Atlantic Ocean from Florida, USA, to southern Brazil. It can reach a length of around three metres. It feeds almost exclusively on fish. The remora is a fish that specialises in living on other fish. It has a suction disc modified from its dorsal fin, which it uses to stick itself to the skin of larger animals, such as sharks, turtles and whales. The remora then feeds on scraps that its host leaves when feeding. The host is not affected. This type of relationship is called commensalism.
