Study Notes

Animal Classification

Species: A group of animals that share common characteristics and resemble each other more than they do other groups.
Classification: The systematic process of organizing living things into categories based on similarities and common ancestry.

Temperature Regulation

Warm-blooded: Animals that maintain their own body heat regardless of external temperatures (e.g., mammals, birds like elephants and eagles).
Cold-blooded: Animals whose body temperature varies with the environment (e.g., reptiles, amphibians, fish).

Animal Groups

Invertebrates: Animals lacking a backbone, including molluscs, sponges, arthropods, worms, and jellyfish.
Vertebrates: Animals with a backbone, divided into categories such as mammals, fish, birds, reptiles, and amphibians.

Mammals

Definition: Warm-blooded vertebrates that nourish young with milk from mammary glands; usually have hair and give birth to live young.
Characteristics:
- Have four limbs (except whales)
- Possess seven neck bones (except sea cows and sloths)
- Breathe using lungs
- Can sweat or pant to release heat
- Young mammals learn from their mothers
Mammal Examples: Dolphins, whales, humans, dogs, cats, horses, kangaroos, lions, tigers, giraffes, elephants, bats, and polar bears.

Birds

Definition: Warm-blooded vertebrates that lay eggs with hard shells, covered in feathers, typically with the ability to fly.
Characteristics:
- Two limbs adapted for flight, beaks, vertebrae, and hollow bones.
Bird Examples: Ravens, eagles, hawks, owls, ducks, geese, swans, penguins, and ostriches.

Fish

Definition: Cold-blooded vertebrates living in water, characterized by gills for breathing, fins for movement, and scaly bodies.
Characteristics:
- Usually lay eggs with soft shells
- Have no limbs, only fins
- Some have cartilage-based skeletons
Fish Examples: Piranhas, seahorses, sharks, whale sharks, lion fish. Notable non-fish include whales and dolphins (which are mammals).

Reptiles

Definition: Cold-blooded, air-breathing vertebrates that typically lay eggs with leathery shells, have skin covered with scales.
Characteristics:
- Can have no legs or four legs with claws
- Breathe using lungs
Reptile Examples: Snakes, lizards, crocodiles, alligators, turtles.

Arthropods

Definition: Invertebrates with segmented bodies, hard exoskeletons, jointed limbs, and usually cold-blooded.
Characteristics:
- Show diversity with many classes (11 in total)
- Most have the ability to fly
- Breathe through tubes
Arthropod Examples: Spiders, millipedes, ants, bumblebees, crabs, centipedes, mites, ticks, shrimp, krill, scorpions, barnacles.

Amphibians

Definition: Cold-blooded vertebrates capable of living both in water and on land, often seen as a transition between fish and reptiles.
Characteristics:
- Lay unshelled eggs
- Typically include frogs and salamanders.
