Aquatic animals that strain floating plants and from the water they take in are?

The aquatic animals that strain floating plants and food particles from the water they take in are called filter feeders.

Here are some examples:

* Whales: Baleen whales like humpback whales have baleen plates instead of teeth. They take in large amounts of water containing krill and other small organisms, then push the water out through the baleen plates, trapping the food inside.

* Fish: Some fish, like herring and sardines, have gill rakers that act like filters, trapping small organisms and phytoplankton from the water.

* Clams and mussels: These bivalve mollusks filter water through their gills, trapping algae and other food particles.

* Barnacles: These crustaceans use their feathery legs to filter water and capture microscopic organisms.

* Sponges: These simple animals filter water through their porous bodies, capturing bacteria and other small food items.

Filter feeders play a vital role in aquatic ecosystems by keeping the water clean and contributing to the food chain.
