Justification:
|
A modest-sized shark widespread in warm-temperate, subtropical and tropical waters world-wide. It frequents inshore waters as adults and has inshore nursery areas, making it highly vulnerable to fishing pressure and human-induced habitat alteration. Frequently captured in commercial and recreational fisheries, its meat is valuable and fins highly marketable.

Habitat and Ecology
|
Habitat and Ecology:
|
This shark occurs on or adjacent to continental and insular shelves, commonly entering inshore waters in estuaries, shallow muddy bays, and island lagoons. Although it can tolerate the reduced salinities of estuaries and river mouths, does not venture any further into riverine systems. It is a very active species, occurring in large schools in surface waters. The main part of the diet consists of bony fish, with some cephalopods and crustaceans. Smaller sharks, skates, and rays may also be taken.

Threats
|
Threats:
|
The main threats to the blacktip shark are pressures from both commercial and recreational fisheries. Its meat is sold fresh, fresh-frozen, or dried salted for human consumption; fins are highly marketable; hides are used for leather; liver oil is used for its high vitamin content; and carcasses are used for fishmeal. Human-induced habitat alteration has also has also been reported as a threat to the species.
