- Some animals use camouflage (e.g., chameleon, zebra, arctic fox, polar bear, frog) to hide from predators
- Camouflage involves blending with the surroundings
Animals in Danger
- Many animals are endangered due to human activities
- Deforestation destroys habitats and food sources for animals
- Some animals, like the Dodo and passenger pigeon, are extinct (no longer exist)
- Animals like the Giant Panda and tiger are endangered (at risk of extinction)
- Endangered animals need protection to prevent extinction
Types of Animals
- Terrestrial animals: Animals that live on land
- Aerial animals: Animals that spend a lot of time in the air (e.g., birds, bats)
- Herbivores: Animals that eat plants
- Carnivores: Animals that eat meat
- Omnivores: Animals that eat both plants and meat
- Scavengers: Animals that feed on dead animals
- Parasites: Animals that live on or in a host and feed on it
Animals' Habitats and Protection
- Animals adapt to different environments (e.g., thick skin in hot climates)
