Killer whales are apex predators throughout their global distribution, and can have a profound effect on the behavior and population of prey species. Their diet is very broad and they can feed on many vertebrates in the ocean including salmon, [82] rays, sharks (even white sharks), [83] [84] large baleen whales, [85] and nearly 20 species of ...
The giant trevally is one of the most important apex predators in its habitats, both as adults on reefs and as juveniles in estuaries. [34] Observations in relatively untouched waters of the northwestern Hawaiian Islands showed the giant trevally was of high ecological importance, constituting 71% of the apex predator biomass , and was the ...
