The aquatic world is a vast repository of natural polymers. Aquatic mammals have several proteins in them. Whales are no exception. The teeth of a whale are rich in baleen, a natural polymer.
Baleen is made up of keratin, a type of protein. It is strong, durable and flexible. Keratin is generally of two types – hard and soft. Hard keratin is usually found in human fingernails, hair and claws of birds. Soft keratin is found in whale bone. Another prominent polymer obtained from a whale is leather. Leather is processed from its skin and has a variety of applications.
