The drop-off zone applies mainly to the reefs surrounding oceanic islands and atolls. "[The grey reef shark] ...shows microhabitat separation from the blacktip reef sharks; around islands where both species occur, the blacktip occupies shallow flats, while the grey reef shark is usually found in deeper areas, but where the blacktip is absent, the grey reef shark is commonly found on the flats... [The grey reef shark] complements the whitetip shark as it is far more adapt at catching off-bottom fish than the whitetip, but the later is far more competent in extracting prey from crevices and holes in reefs."[52].
