Baleen is a filter-feeding system inside the mouths of baleen whales. The baleen system works by a whale taking in water; the whale pushes the water out, animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails and hair. Baleen is a skin derivative; some whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen; these baleen bristles are arranged in plates across the upper jaw of whales. Depending on the species, a baleen plate can be 0.5 to 3.5 m long, weigh up to 90 kg. Its hairy fringes are called whalebone hair, they are called baleen bristles, which in sei whales are calcified, with calcification functioning to increase their stiffness. Baleen plates are broader at the gumline; the plates have been compared to Venetian blinds. As a material for various human uses, baleen is called whalebone, a misnomer.
The word "baleen" derives from the Latin bālaena, related to the Greek phalaina – both of which mean "whale". The oldest true fossils of baleen are only 15 million years old because baleen fossilizes, scientists believe it originated earlier than that; this is indicated by baleen-related skull modifications being found in fossils from earlier, including a buttress of bone in the upper jaw beneath the eyes, loose lower jaw bones at the chin. Baleen is believed to have evolved around 30 million years ago from a hard, gummy upper jaw, like the one a Dall's porpoise has; the initial evolution and radiation of baleen plates is believed to have occurred during Early Oligocene when Antarctica broke off from Gondwana and the Antarctic Circumpolar Current was formed, increasing productivity of ocean environments. This occurred because the current kept warm ocean waters away from the area, now Antarctica, producing steep gradients in temperature, salinity and nutrients, where the warm water meets the cold.
The transition from teeth to baleen is proposed to have occurred stepwise, from teeth to a hybrid to baleen. It is known that modern mysticetes have teeth and develop baleen plate germs in utero, but lose their dentition and have only baleen during their juvenile years and adulthood. However, developing mysticetes do not produce tooth enamel because at some point this trait evolved to become a pseudogene; this is to have occurred about 28 million years ago and proves that dentition is an ancestral state of mysticetes. Using parsimony to study this and other ancestral characters suggests that the common ancestor of aetiocetids and edentulous mysticetes evolved lateral nutrient foramina, which are believed to have provided blood vessels and nerves a way to reach developing baleen. Further research suggests that the baleen of Aetiocetus was arranged in bundles between spaced teeth. If true, this combination of baleen and dentition in Aetiocetus would act as a transition state between odontocetes and mysticetes.
This intermediate step is further supported by evidence of other changes that occurred with the evolution of baleen that make it possible for the organisms to survive using filter feeding, such as a change in skull structure and throat elasticity. It would be unlikely for all of these changes to occur at once. Therefore, it is proposed that Oligocene aetiocetids possess both ancestral and descendant character states regarding feeding strategies; this makes them mosaic taxa, showing that either baleen evolved before dentition was lost or that the traits for filter feeding evolved for other functions. It shows that the evolution could have occurred because the ancestral state was maintained. Therefore, the mosaic whales could have exploited new resources using filter feeding while not abandoning their previous prey strategies; the result of this stepwise transition is apparent in modern-day baleen whales, because of their enamel pseudogenes and their in utero development and reabsorbing of teeth.
If it is true that many early baleen whales had teeth, these were used only peripherally, or not at all. Intense research has been carried out to sort out the evolution and phylogenetic history of mysticetes, but much debate surrounds this issue. A whale's baleen plates play the most important role in its filter-feeding process. To feed, a baleen whale opens its mouth and scoops in dense shoals of prey, together with large volumes of water, it partly shuts its mouth and presses its tongue against its upper jaw, forcing the water to pass out sideways through the baleen, thus sieving out the prey, which it swallows. Whale baleen is the mineralized keratin-based bio-material consisting of parallel plates suspended down the mouth of the whale. Baleen's mechanical properties being strong and flexible made it a popular material for numerous applications requiring such a property; the basic structure of the whale baleen was characterized to be a tubular structure with a medulla hollow core enclosed by a tubular layer with a diameter varying from 60 to 900 microns, which had 2.7 times higher calcium content.
