Oysters eat plankton, algae and small food particles that wash over their gills. Both oysters and clams use the same type of siphoning and straining system to remove food from the water around them.Continue Reading
When water washes over an oyster, it pushes the water through its body and extracts any plankton or small particles of water vegetation. Oysters are called filter feeders because they essentially filter their food out of the water.
The food that an oyster eats can affect what a person finds when opening the oyster. Depending on the color of the algae eaten, an oyster may have green or red coloring inside.Learn more about Marine Life
Prawns are omnivorous, and in the wild they eat a variety of food, including plankton, carrion and other microorganisms. Their diet also consists of detritus, or fragments of decaying organic matter, small shellfish and worms.Full Answer >
Depending on the sponge, food is obtained through filtering water for nutrient-rich particles or snaring small sea creatures with specially adapted arms. Most sponges are detritivorous, consuming debris particles and microscopic life forms that float their way.Full Answer >
Digestion in porifera, or sponges, occurs in individual cells, which envelop and break down food particles. Sponges lack tissues, organs and organ systems, so they don't have the same digestive systems as more complex animals. The food particles absorbed are tiny and include single-celled plankton, bacteria, fragments of larger organisms and particles of waste matter.Full Answer >
According to A-Z animals, barnacles are primarily filter feeders that collect microscopic particles of food from the water column. These food particles can be comprised of plankton or bits of organic debris.Full Answer >
