What Is a Seahorse's Food Chain?

Seahorses occupy a middle position in their food chain. They are carnivores that feed on tiny crustaceans, such as shrimp. The shrimp feed on algae, which are near the base of the food chain. Seahorses are preyed upon by crabs and fish, which are eaten by larger fish. These large fish are hunted by apex predators, including sharks that are at the top of the food chain.
