What does the whitetip shark eat?

During the day they can spend a lot of time resting, because unlike other sharks they do not have to constantly swim to breathe. This species has the ability to pump water over its gills in order to remain immobile on the bottom.

It is at night when whitetip sharks hunt, usually in groups. although each shark hunts individually and in competition with others in its group. Whitetip reef sharks do not tend to become agitated or frantic when feeding in groups.

The characteristics of their elongated bodies make it easier for them to extract the fish hidden in holes or crevices, and although their body is favorable for obtaining prey inaccessible to other species of reef shark, they are somewhat clumsy to catch food floating in open water.

It mainly feeds on fish, such as eel, parrotfish, triggerfish, as well as octopuses, lobsters, and crabs.

This species excellently captures smells, sounds and because of their prey, they have a more developed sense of sight to capture movements than to distinguish details.

Moving from their nocturnal habits, these sharks also hunt during the day if they find easy prey.
