Filter feeders in the ocean filter water through their body to eat. They filter phytoplankton out of the water to gain nutrients.
plankton
filter feeders like clams, sponges, krill, baleen whales, fishes, and many others fill the ocean, spending their days filtering and eating tiny particles from the water.
They use cilia to pull water into the shells and over their gills, which are covered with a thick mucus lining. Small organisms and organic material that have been floating in the water get stuck the the mucus, which flows into the mouth. Hope this helped! :]
I may be a little off but they are filter feeders. The cilia transports the water then the mucus collects the food and finally the cilia transports that to the GI tract. Hope that helps
Extremely small single cell organisms
As we know it, filter feeders in the oceans live on plankton . These really small organisms thrive in all the oceans .
Most filter feeders eat plankton or zooplankton. Filter feeders can include sponges, herring fish, and baleen whales. Filter feeders obtain their food by straining food particles or organisms from the water around them
Yes, sponges are filter feeders. I also believe they were the first filter feeders.
Clams are filter feeders because they filter stuff.
Blue whales are filter feeders; they filter small organisms such as krill, sardines, etc, out of the water, by use of their baleens.
Tuna fish are not filter feeders. Tuna usually eat surface fish, or even lancetfish. They may also eat other tuna.
they eat random sh** floating in the water such as microcopic organisms. they are filter feeders.
No, filter feeders in general do not have teeth. Piranha do not filter their food.
Filter feeders are organisms that are mainly found underwater. They eat using the method of 'filter feeding' where-by they simply just open their mouth and take in whatever happens to be their (nutrients in water), whilst filtering the undesirable parts.
filter feeders! : )
Filter feeders and fluid feeders are alike in a great number of ways. These animals both sift for food to eat.
