Mammals Body Covering
mammals body covering. You can if a animal is a mammal when it has a lot of fur . some types of mammals are wolves, foxes, deer, bull, monkeys, and beavers. humans are considered as mammals we have a little fur but that still means we are mammals. All mammals, living and extinct, share certain traits in common because they're all descended from a common ancestor. These traits include having fur and producing milk to nourish their young. By ancestry. But all mammals—and only mammals—have three bones inside the middle ear. This is one of the ways scientists recognize a mammal, along with tracing their evolutionary history back to a common ancestor and looking at the traits they share because of this. Different kinds of teeth can be specialized for diet. Mammals use incisors to grab, slice or cut their food, and canines, premolars and molars for a variety of functions, such as to slice, grind food, shear meat or crush bone. Mammals use hair for insulation, which is associated with warm-bloodedness (endothermy); wooing mates; fending off predators for camouflage; and, in the case of whiskers, navigating through darkness or narrow spaces. Examples include giant rodents; lemurs found only on the island of Madagascar; huge plant-eaters; or gliding opossums. Dwarf elephants, water buffaloes, and pygmy hippos all evolved on isolated islands or continents. information got from http://www.amnh.org/education/resources/rfl/web/extrememammalsguide/questions.html
Mammals have several unique characteristics that differentiate them from other animals. Most mammals have hair, or fur, covering their body. They are also capable of regulating their body temperature. The mammals metabolism controls heat production, and the sweat glands help cool the body. These allow the mammal to maintain a constant body temperature, regardless of the environmental temperature. One other difference is that mammals give birth to fully formed babies, and the female mammals produce milk to feed their young.
Most mammals walk on 4 legs, with only the humans walking upright on 2 legs. Aquatic mammals have flippers, or fins, for swimming rather than legs. Common mammals include: primates, such humans and monkeys; marsupials; rodents; whales; dolphins; and, seals.
