The Blacktip reef Shark (Carcharhinus melanopterus) is a species of requiem shark, in the family Carcharhinidae, which can be easily identified by the prominent black tips on its fins (especially on the first dorsal fin and its caudal fin). Among the most abundant sharks inhabiting the tropical coral reefs of the Indian and Pacific Oceans, this species prefers shallow, inshore waters. Its exposed first dorsal fin is a common sight in the region. The blacktip reef shark is usually found over reef ledges and sandy flats, though it has also been known to enter brakish and freshwater environments.

The Catshark is a predominantly nocturnal fish that hides in the burrows and ravines of submerged cliffs during the day.

In this case, as there were no Gorgonians in the seabed, he used the rope abandoned on the bottom by a boat.
