  1. Mammals Like You!

  2. So What’s a Mammal? • Fur & sweat glands • Mammary glands (milk) • Endothermic

  3. Class Mammalia Subclasses: • Monotremes • 5 egg laying species, including platypus. • Marsupials • females carry young in pouch after short gestation • Placentals • Live young born at large size, no pouch.

  4. Carnivora Rodents Primates Shrews Bats

  5. Rodents • Rodentia is an order of mammals also known as rodents, characterised by two continuously growing incisors in the upper and lower jaws which must be kept short by gnawing.[1][2] • Forty percent of mammal species are rodents, and they are found in vast numbers on all continents other than Antarctica. Common rodents include mice, rats, squirrels, porcupines, beavers, chipmunks, guinea pigs, and voles.[1] Rodents have sharp incisors that they use to gnaw wood, break into food, and bite predators. Most eat seeds or plants, though some have more varied diets. Some species have historically been pests, eating seeds stored by people[3] and spreading disease[4]. • The name comes from the Latin word rodere "to gnaw".

  6. Capybera: the 80 kg rodent

  7. Eastern Grey Squirrel

  8. Rattusrattus (no joke)

  9. Bats: Order Chiroptera

  10. Bats: Flying Mammals • Most eat insects, many others eat fruit. • Nocturnal, use sound and hearing to hunt. • Some feed on the blood of mammals

  11. Bat Wings • Bat wings are adapted hand structures

  12. Order Soricomorpha: shrews, moles, and Allies • Similar to rodents in appearance and habits. • Key difference: teeth are pointy and don’t grow continuously.

  13. Order Carnivora: The Carnivores • Members have sharp claws, sharp canine teeth, and digestive system designed for a diet of mostly meat

  14. Families in Order Carnivora • Carnivora includes many familiar families of mammals, including: • Felines • Canines • Bears (ursaforms) • Others (mongooses, racoons, walruses, etc.)

  15. The Primates • Mandrill pictured

  16. What makes a Primate? • A partial list of primate characteristics: • 5 digits including opposable thumbs. • Highly developed color vision • Enlarged, differentiated cerebral cortex (big brains) • 3 kinds of teeth, 2 pectoral mammary glands. • Many others…
