How Do We Classify Animals? By Sonya Cameron
Things to look at Some animals are vertebrates: have backbone. Some are invertebrates : do not have a backbone. Are they warm blooded: the temperature of their blood does not change with environment. Are they cold blooded: The temperature of their blood changes.
Do they breath through lungs or gills? Where do they live? Do they have hair? What do they look like? What type of symmetry do they have? (Symmetry is matching pattern of body shape). How do they get their energy (what do they eat)?
Look at All the Different Animals How Can We Group Them?
Invertebrates Most animals are invertebrates: They have no back bone. Types of invertebrates: Cnidarians (jelly fish and coral) Cnidarians have a simple digestive system with a mouth. They also have radial symmetry (their parts repeat around a center). Echinoderms (star fish and sea cucumber) They have spiky skin and usually have suckers. Sponges (ocean animals with no tissues, organs, or body symmetry).
Arthropods: (Lobsters, crabs, and insects) They have a hard covering called an exoskeleton and bilateral symmetry (left side looks like right). Mollusks: (clams and oysters, squid, snail, and octopuses). They have soft bodies but some have shells. Worms
Vertebrates: Have backbones and include dogs, cats, humans, birds, alligators, and more.
Carnivore: Eats meat only Herbivore: Eats plants only Omnivore: Eats plants and meat Scavengers: Eat the remains of recently dead organisms
Predators and Prey Predators hunt other animals for food. Animals of Prey are animals that are hunted for food. Can you name some animals that are predators? Can you name some animals that are prey?
Scientists classify animals into six groups Mammals Reptiles Amphibians Birds Insects Fish
Mammals Have fur or hair Breathe with lungs Female mammals make milk for their babies
Examples of Mammals What others can you name?
Reptiles Have scaly skin Most reptiles lay eggs Live in dry or wet habitats
Examples of Reptiles
Amphibians Begin their lives in water Have smooth, moist skin Live in both water and land
Examples of Amphibians
Birds Only animals with feathers Have two wings and two legs Young hatches from eggs
Examples of Birds
Insects Have three body parts and six legs Have hard body coverings Young hatch from eggs
Examples of Insects
Fish Live in water Breathe with gills Have fins to move through water
Examples of Fish
