They are known to be opportunistic predators, feeding on a variety of prey items including small fish, crustaceans, and cephalopods. The trophic interactions of blacktip sharks have been the subject of much research, with some studies suggesting that they may play a key role in trophic cascades in certain ecosystems.

A trophic cascade is a phenomenon where changes at one trophic level in a food web can have cascading effects throughout the ecosystem. In marine ecosystems, trophic cascades can occur when predators at the top of the food chain exert top-down control on prey populations, which in turn affects the abundance and distribution of lower trophic levels.

Blacktip sharks have been identified as potential keystone species in some marine ecosystems, meaning that their removal could have significant impacts on the structure and function of the ecosystem. For example, a study conducted in a shallow subtropical estuary in the western Gulf of Mexico found that blacktip sharks were the dominant predator in the system, and that their presence had significant effects on the abundance and distribution of their prey species.

In this ecosystem, blacktip sharks primarily fed on clupeids and sciaenids, which made up 69% of their diet. The removal of blacktip sharks from the system resulted in an increase in the abundance of these prey species, which in turn led to a decrease in the abundance of their own prey items, such as mysids and penaeid shrimp.

Overall, these findings suggest that blacktip sharks may play an important role in trophic cascades in certain marine ecosystems, particularly those where they are the dominant predator. Their position in the food chain and their feeding behavior make them well-suited to exert top-down control on prey populations, which can have far-reaching effects on the structure and function of the ecosystem.

Keystone Species Role of Blacktip Sharks
