Piscivorous (fish-eating) Birds: Birds such as osprey, herons, egrets, and pelicans are often found in lagoons and prey on smaller fish.
Sharks and Rays: Depending on the lagoon's connection to the ocean, you may find sharks and rays swimming close to shore, preying on smaller fish, crustaceans, and mollusks.
Large Carnivorous Fish: Some lagoons may have large predatory fish such as barracuda, snook, and tarpon. These fish prey on smaller fish, squid, and crustaceans.
Marine Mammals: In coastal lagoons, marine mammals like dolphins and seals can hunt and feed on various fish, squid, and crustaceans within the lagoon.
Crocodiles and Alligators: In tropical and subtropical lagoons, you may find crocodiles or alligators. They are apex predators, preying on fish, amphibians, reptiles, birds, and even small mammals.
It's important to note that the presence and composition of top predators in a particular lagoon can be influenced by factors like water salinity, lagoon size, habitat availability, and human activities in the area.
