Triaenodon obesus is a reef shark as its name would indicate and lives in or around coral reefs. These reef settings are in tropical, coastal waters. Being a nocturnal animal, it spends much of the day in caves and deep crevices in coral reefs or coral reef lagoons. Whitetip reef sharks share these habitats with other reef sharks. However each species takes on a particular location within the reef system. The blacktip reef shark takes the shallow, high-energy coastal waters. The grey reef shark takes the deeper clear waters off the reef edge. The whitetip reef shark is the shark that lives in among the coral reefs, most commonly between the depths of 8 and 40 meters.
