What is another word for baleens?
Pronunciation: [bˈaliːnz] (IPA) 
Baleens refer to the keratinous plates that hang like a fringe from the upper jawbone of large marine mammals such as whales. These structures are used to filter-feed small organisms, including krill, plankton, and other small fish. Although baleens are commonly known as whalebone, these structures are not bones but are made up of the same material as our fingernails and hair. There are several synonyms for baleens, including whale teeth, whalebone plates, baleen plates, and horny plates, all of which refer to the same structure. The use of baleens by whales and other marine mammals for feeding and survival is a remarkable adaptation, reflecting the wonders of nature.
