Filter feeders (also known as suspension feeders) are animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized structure, such as the baleen of baleen whales. Filter feeding is one of the four major types of feeding. Some animals that use this method of feeding are clams, krill, flamingos, sponges and whale sharks. For other uses, see Animal (disambiguation). ...

Filter feeding in krill

The Antarctic krill manages to directly utilize the minute phytoplankton cells, which no other higher animal of krill size can do. This is accomplished through filter feeding, using the krill's developed front legs, providing for a very efficient filtering apparatus:[1] the six thoracopods form a very effective "feeding basket" used to collect phytoplankton from the open water. In the movie linked to the right, the krill is hovering at a 55° angle on the spot. In lower food concentrations, the feeding basket is pushed through the water for over half a meter in an opened position, and then the algae are combed to the mouth opening with special setae on the inner side of the thoracopods.

These 3 cm long animals live close to shore and hover above the sea floor, constantly collecting particles. They are an important food source for herring, cod, flounder, striped bass. In polluted areas they have in their tissue extremely high toxin levels, they are very robust and take a lot of poison before they die. Such filter feeding organisms are the reason that much of the materials we throw in the oceans comes back to us in our food. mysis zooplankton (Photo by Uwe Kils GFDL) File history Legend: (cur) = this is the current file, (del) = delete this old version, (rev) = revert to this old version. ... mysis zooplankton (Photo by Uwe Kils GFDL) File history Legend: (cur) = this is the current file, (del) = delete this old version, (rev) = revert to this old version. ...
