Describe resource partitioning by and the various niches of reef fishes. Consider the fishes at the family level, highlighting at least 10 of the following dominant families: boxfishes, butterflyfishes, damselfishes, eels, filefishes, flatfishes, goatfishes, groupers, hawkfishes, needlefishes and halfbeaks, parrotfishes, porcupinefishes, pufferfishes, surgeonfishes, triggerfishes, trumpetfishes, and wrasses.

Grey reef sharks are crepuscular so they are most active at dawn and dusk. They specialize in foraging at depths below 20 meters in both forereef and backreef environments. Grey reef sharks will leave the reef at night to forage in the pelagic zone and dive to grater depths. For the most part resting, foraging and any possible social behaviors all occur in close to the reef.
