- 2. CLASSIFICATION OF ANIMALS ACCORDING TO: THEFOOD THEY EAT CARNIVORES HERBIVORES OMNIVORES They eat other animals They eat plants and fruits They eat both animals and plants
- 3. CLASSIFICATION OF ANIMALS ACCORDING TO: HOWTHEY ARE BORN VIVIPAROUS OVIPAROUS They grow inside their mother’s body and they are born alive. They lay eggs and the babies grow inside the eggs until they are ready to come out.
- 4. CLASSIFICATION OF ANIMALS ACCORDING TO: STRUCTURE INVERTEBRATES VERTEBRATES Theyhave got a backbone. There are less than 10% vertebrate animals on Earth. They haven’t got a backbone. Over 90% of the animals on Earth are invertebrates.
- 5. INVERTEBRATES ARTHROPODS • Arachnids • Crustaceans •Insects •Myriapods Animalswithout a backbone. MOLLUSCS ECHINODERMS SPONGES
- 6. VERTEBRATES Animals witha backbone. MAMMALS They can live on land (lion), in water (dolphin) or they can fly (bat). They have got fur. They are warm blooded. They breath through lungs. They have got a skeleton with a backbone and a skull (cranium). They drink their mother’s milk until they are old enough to eat other food. Humans are also mammals. They are viviparous. The only exception are monotrems (oviparous mammals).
- 7. VERTEBRATES Animals witha backbone. BIRDS They are oviparous. They lay eggs. They have a beak, feathers and wings, but not all birds can fly. REPTILES They are generally oviparous, but there are some ovoviviparous reptiles. They have got scales and dry skin. They are cold-blooded AMPHIBIANS They are oviparous. They lay eggs in the water. They have got wet skin. They are cold- blooded. Amphibian means "double life”. They live in water when they are babies and on land. Think of a tadpole turning into a frog! The process amphibians go through is called "metamorphosis". Baby amphibians look completely different to adult amphibians!
- 8. FISH VERTEBRATES Animals witha backbone. They are generally oviparous. They lay many tiny eggs in the water. They live in water but they can breathe using gills, not lungs. They have scales and fins. They are cold-blooded.
