filter feeding
Filter feeding is a method used by various aquatic animals to obtain food. These animals, such as whales, clams, and sponges, draw in water and trap tiny particles like plankton and detritus using specialized structures. This process allows them to efficiently consume large amounts of food while filtering out unwanted materials.
The filter feeding process typically involves the animal creating a current in the water, which brings in food particles. For example, baleen whales use baleen plates to strain food from the water, while oysters filter water through their gills. This feeding strategy is essential for maintaining healthy ecosystems by recycling nutrients.
