A Caribbean reef shark cruising over a coral reef in the Bahamas.​

Despite its abundance in certain areas, the Caribbean reef shark is one of the least-studied large requiem sharks. They are believed to play a major role in shaping Caribbean reef communities. These sharks are more active at night, with no evidence of seasonal changes in activity or migration. Juveniles tend to remain in a localized area throughout the year, while adults range over a wider area.[7]
Caribbean reef sharks are sometimes seen resting motionless on the sea floor or inside caves; it is the first active shark species in which such a behavior was reported. In 1975, Eugenie Clark investigated the famed "sleeping sharks" inside the caves at Isla Mujeres off the Yucatan Peninsula, and determined that the sharks were not actually asleep as their eyes would follow divers. Clark speculated that freshwater upwellings inside the caves might loosen parasites on the sharks and produce an enjoyable "narcotic" effect.[8] If threatened, Caribbean reef sharks sometimes perform a threat display, in which they swim in a short, jerky fashion with frequent changes in direction and repeated, brief (1–1.2 second duration) drops of the pectoral fins. This display is less pronounced than the better-known display of the grey reef shark (C. amblyrhynchos).[8][9]
Juvenile Caribbean reef sharks are preyed upon by larger sharks such as the tiger shark (Galeocerdo cuvier) and the bull shark(C. leucas). Few parasites are known for this species; one is a dark variegated leech often seen trailing from its first dorsal fin.[4]Off northern Brazil, juveniles seek out cleaning stations occupied by yellownose gobies (Elacatinus randalli), which clean the sharks of parasites while they lie still on the bottom.[10] Horse-eye jacks (Caranx latus) and bar jacks (Carangoides ruber) routinely school around Caribbean reef sharks.[11]
