This animal is really active at night.
Indeed, once night has fallen, the whitetip shark hunts small fish, crustaceans or octopus. It frenetically searches for its preys moving as a snake through the coral gardens.
“ It owns an impressive jaw with about 3 000 teeth that renew every three days. ”
This shark is a predator as well as a scavenger. It owns an impressive jaw with about 3 000 teeth that renew every three days. During the day, it is a really “lazy” animal that stay lying on the sandy bottom close to the corals. As you know, a shark has to move to breathe. The whitetip reef shark stay near the current using its power to oxygenate without moving. What an ingenious method !!
You could encounter this inoffensive shark in all Polynesian archipelagos without any difficulties. It is a really common species of the shallow waters, a perfect opportunity for underwater photographers.
