Study Notes
Mammals
Characteristics
- Warm-blooded (endothermic)
- Hair or fur
- Three middle ear bones
- Mammary glands for milk production
- Live young (except for platypus and echidna)
Types of Mammals
- Placental Mammals: Give birth to fully formed young, nourished by a placenta during pregnancy (e.g., humans, dogs, cats)
- Marsupials: Give birth to underdeveloped young, which then complete development inside a pouch (e.g., kangaroo, koala)
- Monotremes: Lay eggs, but also produce milk for their young (e.g., platypus, echidna)
Mammalian Diets
- Herbivores: Plant-eaters (e.g., deer, rabbits, sloths)
- Carnivores: Meat-eaters (e.g., lions, tigers, wolves)
- Omnivores: Eat both plants and animals (e.g., humans, bears, pigs)
Mammalian Adaptations
- Specialized limbs: Wings (bats, flying foxes), flippers (whales, seals), claws (cats, bears)
- Thermoregulation: Ability to regulate body temperature (e.g., sweating, shivering)
- Camouflage: Blending in with surroundings for protection (e.g., polar bears, arctic foxes)
Examples of Mammals
- Large mammals: Elephants, rhinos, hippos, whales
- Small mammals: Mice, rabbits, squirrels, bats
- Marine mammals: Whales, dolphins, seals, walruses
Characteristics of Mammals
- Mammals are warm-blooded (endothermic), meaning they regulate their own body temperature
- Mammals have hair or fur, which helps to insulate and protect their bodies
- Mammals have three middle ear bones, which aid in hearing and balance
- Mammals have mammary glands, which produce milk to nourish their young
- With the exception of platypus and echidna, mammals give birth to live young

Mammalian Diets
Herbivores
- Eat plants as their primary source of nutrition
- Examples: deer, rabbits, sloths
Carnivores
- Eat meat as their primary source of nutrition
- Examples: lions, tigers, wolves
Omnivores
- Eat both plants and animals as their source of nutrition
- Examples: humans, bears, pigs

Specialized Limbs
- Examples: wings (bats, flying foxes), flippers (whales, seals), claws (cats, bears)
