Study Notes
Classification of Mammals
- Mammals belong to the Kingdom Animalia, Phylum Chordata, and Class Mammalia.
- Approximately 5,000 species of living mammals exist today.
- Characteristics of mammals include body hair, three middle ear bones (malleus, incus, stapes), and nourishment of young through milk produced by mammary glands.
Major Mammal Orders
- Major subclasses of mammals include Eutheria (placental mammals), Metatheria (marsupials), and Prototheria (monotremes).
Subclass Eutheria
- Contains placental mammals and has various orders with distinct traits.
Order Artiodactyla
- Comprises even-toed ungulates, around 210 species.
- "Artiodactyl" means "even-number finger or toe," primarily herbivores (Example: Deer).
Order Carnivora
- Includes approximately 270 species known as carnivores.
- Features carnassial teeth important for slicing food (Example: Cats).
Order Cetacea
- Features the largest marine mammals, including blue whales.
- Divided into toothed whales and baleen whales (Examples: Whales, dolphins, porpoises).
Order Lagomorpha
- Consists of two families: Ochotonidae (pikas) and Leporidae (hares and rabbits).
- Mostly herbivorous.
Order Perissodactyla
- Comprises odd-toed ungulates, with the name meaning "odd-number finger or toe."
- Herbivores like rhinoceroses.
Order Pholidota
- Known commonly as "scaly anteater," primarily carnivorous (Example: Pangolin).
Order Primates
- Encompasses about 200 species, including both apes and monkeys.
Order Proboscidea
- Home to the largest land animals, with the African elephant being a prime example.
- The term "proboscis" refers to the long nose.
Order Sirenia
- Exclusively herbivorous, includes marine mammals like manatees.
Order Edentata
- Herbivorous order featuring animals such as sloths.
Order Tubulidentata
- Features aardvarks, with an average captive lifespan of 10 years and primarily carnivorous diet.
Subclass Metatheria
- Encompasses marsupials, which are characterized by their pouch for offspring.
Order Didelphimorphia
- Known as opossums, which are omnivores.
Order Dasyuromorphia
- Features carnivorous species like numbats.
Order Peramelemorphia
- Includes bandicoots, which are omnivorous.
Order Diprotodontia
- Comprising kangaroos as representative herbivores.
Subclass Prototheria
- Represents the monotremes, which are egg-laying mammals.
Order Monotremata
- Family Ornithorhynchidae includes the duck-billed platypus, known for its carnivorous diet.
Order Monotremata
- Family Tachyglossidae consists of spiny anteaters, also carnivorous.
