Feeding Ecology

-

 

Feeding ecology examines the dietary habits and nutritional strategies of organisms and how these influence their interactions within ecosystems.
 
Some marine mammals consume huge numbers of prey items at a time (batch feeding) while others attack and consume prey items singly (raptorial feeding). Many marine mammals forage in large groups while others feed alone.

Larger animals, including some marine snails, fish, reptiles, and mammals, graze  on algae. Filter feeders strain their food (plankton and detritus) directly from the water. Filter feeding animals include animals like bivalves, tube worms, sponges, and even large animals like baleen whales and manta rays.

Sirenians, the only extant herbivorous marine mammals, Graze feeding on marine grasses and algae. Manatees feed on the blades, leaves, and stems of a variety of aquatic and terrestrial plants, including grasses (e.g., water hyacinth and water thyme Hydrilla), sedges, forbs, herbs, and mangroves.
