Estuaries are protected from the full force of the ocean by mudflats, sandspits, and barrier islands. Only certain organisms can survive in estuaries due to high salinity (salt concentration in water) and constantly changing temperatures. Specifically, omnivores shifted their diets from an omnivorous diet that is mainly carnivorous in the oligotrophic estuary to feeding mainly as herbivores in the eutrophic estuary, where prey were scarce and macroalgae were abundant.

Tags: Question 7 . Omnivores. Estuaries are sometimes called bays, lagoons, harbors, or sounds. Few macrobenthic studies have dealt simultaneously with the two major gradients in estuarine benthic habitats: the salinity gradient along the estuary (longitudinal) and the gradients from high intertidal to deep subtidal sites (vertical gradient). They require an expansive habitat and many kilograms of food every day. However, usually plankton are very small and/or microscopic. Estuarine crocodiles also prey on consumers at the third trophic level, such as boars and snakes (and, rarely, people).Estuarine crocodiles are ideally adapted to the brackish water of river estuaries.
