baleen

Cetacean mouth bristles

Baleen is the flexible, comb-like material that hangs from the upper jaws of certain large whales, filtering small prey like krill and plankton from seawater.

These whales—including humpbacks, blue whales, and right whales—are called baleen whales to distinguish them from toothed whales.

The material consists of keratin, the same protein found in human fingernails, and was once harvested commercially for use in corsets, umbrella ribs, and other items requiring flexible stiffness.
