'''Hvalbarder''' is a built in filter-feeder inside of some of the whales. The whale would open its mouth underwater and water would then pour into the whale's mouth. They would then push the water out, but the animals such as '''krill''' would end up as a meal for the whale. Baleen is like bristles, but are the same substance found in fingernails,hair, and the sand-paper like feeling on a cat's tongue. Some whales have longer baleen than others, like the '''bowhead whale'''. Others only use one side of their baleen, like the '''gray whale''' These baleen bristles are arranged in plates across the upper jaw of the whale.
Afhængigt af arten kan en bardeplade blive mellem 0.5 og 3.5 m lang, længst hos [[grønlandshval]]en og veje op til 90 kg. Its hairy fringes are called baleen hair or whalebone-hair. They are also called baleen bristles, which in [[sei whale]]s are highly calcified, calcification functioning to increase their stiffness (Fudge ''et al''. 2009; Szewciw ''et al''. 2010). Baleen plates are broader at the gumline (base). The plates have been compared to [[sieve]]s or [[Window blind#Venetian|Venetian blinds]].
