Baleen can be found in the mouths of certain species of whales, specifically baleen whales, such as the humpback, blue, and gray whales. It is made of keratin, the same protein that forms human hair and nails, and serves as a filter-feeding system to catch small prey like krill and plankton from the water. Baleen plates hang from the upper jaw and can vary in size and shape among different species.
