Information about Filter Feeder
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.
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.

The long comb like setae stretch outwards to cover over the gap between the thoracopods | ) The first order filter setae have attached to them second order setae. The second order setae are aligned in rows, these rows form a v-shape. The v shape of the setae align towards the inside of the feeding basket. (electron microscope image). To display the total area of this fascinating structure one would have to reproduce this tile7500 times. |
) Third order setae form further rows which reduce the gap between the second order setae. This produces a net like structure. In some parts of this structure the gaps between third order setae are only 1 micrometer wide (electron microscope image). |

Filter feeding in whales
The Blue Whale, and example of Baleen whales, feeds by lunging forward at groups of krill, taking the animals and a large quantity of water into the mouth at once. The water is then squeezed out through the baleen plates by pressing the ventral pouch and tongue up against the water. Once the mouth is clear of water, the remaining krill, unable to pass through the plates, are swallowed.See also

Baleen makes up baleen plates, which are arranged in two parallel rows that look like combs of thick hair; they are attached to the upper jaws of baleen whales. It is composed of keratin, which is the same substance that makes up human hair and nails.
