The Blacktip is the species of reef shark commonly seen in Pulau Kapas. The most distinct feature is the rounded apex with black blotches on their first dorsal fin and on their lower lobe of caudal fin. They also have light brown-grey on the top half with white bottom. The adults grow up to 1.6 – 2m, with average females are larger in size compare to the males.
Although generally very timid when approached, the black-tips can be hazardly towards spearfishers and people wading in water. These sharks help balance the ecosystem by preying on a wide variety of organisms. They are able to keep populations in check, allowing animals in the lower part of the food chain to thrive without overpopulating.
