Crack formation is also different for both the transverse and longitudinal orientation. Intense research has been carried out to sort out the evolution and phylogenetic history of mysticetes, but much debate surrounds this issue. 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 approximately 2.7 times higher calcium content. That's the skeleton of a big whale found in Sabata near Malacca. Marc2008. 1 decade ago. The oldest true fossils of baleen are only 15 million years old because baleen rarely fossilizes, and scientists believe it originated considerably earlier than that.

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. [4] This occurred because the current kept warm ocean waters away from the area that is now Antarctica, producing steep gradients in temperature, salinity, light, and nutrients, where the warm water meets the cold.

Check Price. The second, also fairly thick and heavy but obvious fibrous "grain" on one side, has a straight v-shaped crease (about 1/8" deep) the length of the piece. How long does a blue whale live? It is known that modern mysticetes have teeth initially and then develop baleen plate germs in utero, but lose their dentition and have only baleen during their juvenile years and adulthood. So, whales, don’t have hollow bones because water does carry their weight, in fact, sea animals have more dense bones, stronger bones, because they don’t need to spend that much energy moving around.

Many bones are hollow. Further research suggests that the baleen of Aetiocetus was arranged in bundles between widely spaced teeth. 2. Like other mammals these marine animals require oxygen to breathe, eyes to see, ears to hear and mammary glands to feed their young among other things. 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. Baleen's mechanical properties being strong and flexible made it a popular material for numerous applications requiring such a property (see Human uses section). But bones, real bones, stay awhile. Baleen is a skin derivative. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness.

The word "baleen" derives from the Latin bālaena, related to the Greek phalaina – both of which mean "whale". Therefore, it is proposed that Oligocene aetiocetids possess both ancestral and descendant character states regarding feeding strategies. Their hollowness makes bones strong and light. Whale Baculum. At … If it is true that many early baleen whales also had teeth, these were probably used only peripherally, or perhaps not at all (again like Dall's porpoise, which catches squid and fish by gripping them against its hard upper jaw).
