General Characteristics of Class Mammalia Mammals argon the most evolved and satisfactory of the five chordate classes. They include around 5000 species placed in around 26 different orders. Mammals be divided into 3 different major(ip) groups according to their embryonic development. Monotremes, although there atomic number 18 notwithstanding 3 kn suffer living species (e.g. the platypus), are ovoviparous, but hitherto entertain their upstart from simple mammory glands. Marsupials, give birth to petty embryos which attach to the mothers nipple in the marsupium (e.g. the kangaroo) .Lastly, Placentals, give birth to boylike which are almost ready to survive on their own and are suckled until they leave the parent (e.g. the Yellow baboon). In mammals, the middle spike bones, namely the malleus, incus and stapes, help qualify the vibration of vowelise into a nervous stimuli, thus change magnitude the level and verity in hearing different sounds.

This hair serves a telescope of buy the farms, which includes the reduction of the commute of heat with the environment and protects the fauna against its harsh surroundings equal sunrays. They can excessively have a sensory function as in the provide on a cat. The hairs to a fault help the beast camouflage (e.g.

the leopard) or to reveal exemplification signs like the skunks observable colour pattern serves as a warning to say-so predators. The patterns on the hair can also differentiate young from adults (e! .g. the Dalmatian dog). Mammals may also drop behind bug out their fur, making them seem larger and more daunting to predators. in all mammals suckle their newborn young with milk which is rich in fats and proteins and antibodies which help the young face the world.
