Classes of Mammalia
Mammalia: Tetrapoda: Monotreme
Native only to Tasmania and eastern and southern Australia, the platypus is the sole member of the mammal family Ornithorhynchidae.
It is one of two animals that form the order Monotremata (egg-laying mammals), the other being Australia's spiny anteater.
The platypus, also known as the duckbill, watermole, or duckmole, is a shy, reclusive animal that lives near lakes and streams.
The female has no nipples; instead, milk oozes through slits in her abdomen where it is licked up by the young.
Tetrapoda: Mammalia: Marsupials
Mammals that carry their young in an abdominal pouch during their early development are called marsupials. Soon after the marsupial ovum, or egg, is fertilized, the young are born in a premature state and crawl into the mother's pouch. There, nursing on milk from their mother's nipples, they complete their development.
Opossum
Mammalia: Insectovora and Dermoptera
Insectivora (insect eaters). Shrews, Dermoptera. Colugos or flying lemurs. moles, hedgehogs.
Shrew
Mole
Mammalia: Chiroptera and Primates
Chiroptera. Bats. Primates. Tree shrews, monkeys, marmosets, great apes, humans.
Mammalia: Edentata and Pholidita
Edentata. (toothless)Sloths, armadillos, anteaters
.
Entirely covered with large, brown, overlapping scales, the pangolin is well protected against predators. When threatened, the pangolin rolls into a tight ball, causing the sharp, free edges of the scales to rise. Pangolins eat ants and termites, which they lap up with their long, sticky tongues
Pholidota. Pangolins or scaly anteaters
Mammalia: Lagomorpha and Rodentia
Rodentia (gnawers). Mice, rats, squirrels, porcupines, beavers.
Lagomorpha. Hares, rabbits, pikas, plant-eating mammals characterized by a short tail and two pairs of upper incisors, one behind the other.
Mammalia: Cetacea
Cetacea. Dolphins, porpoises, whales, nearly hairless, fishlike water mammals, lacking external hind limbs, but having paddlelike forelimbs.
Mammalia: Pinnipedia and Tubulidenta
Pinnipedia. (finned feet) Seals, sea lions, walruses.
Aardvarks are classified in an order by themselves, the Tubulidentata, meaning "tube-toothed." The tubular teeth are without enamel or roots.
Mammalia: Proboscidea and Hyracoidea
Proboscidea. Elephants, large mammals having tusks and a long, flexible, tubelike snout
.Hyracoidea. Hyraxes, dassiesThe hyrax looks similar to a large rabbit, but is actually more closely related to horses and elephants. It is found in Africa and parts of the Middle East.
Mammalia: Sirenia The manatee is a slow-moving, seal-shaped
mammal that lives in shallow coastal waters or rivers with rich plant growths. Manatees frequently communicate by muzzle-to-muzzle contact and, when alarmed, emit chirpy squeaks. All three species the Caribbean, Amazonian, and African manatees are declining in population because they have been heavily hunted. Adults may grow to lengths of 15 feet (4.6 meters). They are stout, thick-skinned, and almost hairless with a broad, shovellike tail. They have only one pair of limbs weak front flippers which they use to push algae, such as seaweed and other water plants toward their mouths.
Mammalia: Perissodactyla
Perissodactyla (odd-toed hoofed animals). Horses, asses, zebras, tapirs, rhinoceroses.
Tapir
Zebra
Kiangs
