Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale.

All baleen whales have baleen instead of teeth which they use to collect shrimp-like krill, plankton and small fish from the sea. These bristly baleen plates filter, sift, sieve or trap the whales’ favourite prey from seawater inside their mouths. Baleen is made out of keratin, the same protein that makes up our fingernails and hair.

Baleen is the series of fringed plates hanging in their mouths that they use to strain the seawater for food. Baleen was used in a number of consumer products, such as corsets. Here, a researcher examines the baleen from a whale that washed up on the beach.

The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph).
