Mini Lesson

An adaptation is a special feature or behavior that helps an animal survive in its habitat. Over time, animals develop adaptations that suit the conditions of where they live — whether in a desert, ocean, Arctic, or underground.

Types of Adaptations

  • Camouflage — body color or pattern that matches the surroundings to hide from predators.
  • Body shape — a streamlined body that helps an animal move efficiently.
  • Special features — unique body parts such as gills, claws, or a hump that help survival.
  • Behavior — actions such as hibernation or migration that help animals survive harsh conditions.

Animal Adaptation Examples

  • Camel — stores fat in its hump for energy; broad feet spread weight on sand.
  • Polar bear — thick white fur for insulation and camouflage in snow.
  • Duck — webbed feet for swimming; waterproof feathers.
  • Mole — large front claws for digging tunnels underground.
  • Eagle — sharp talons and excellent eyesight to spot and catch prey.
  • Arctic fox — white coat in winter for camouflage in snow.

Words to know

Adaptation

A special feature or behavior that helps an animal survive in its habitat

e.g. Thick fur is an adaptation for cold places.

Habitat

The natural place where an animal or plant lives

e.g. A polar bear's habitat is the snowy Arctic.

Camouflage

Body color or pattern that helps an animal blend in with its surroundings

e.g. A green grasshopper uses camouflage in the grass.

Predator

An animal that hunts and eats other animals

e.g. An eagle is a predator with sharp talons.

Hibernation

A long, deep sleep some animals enter during cold winter months

e.g. Bears use hibernation to survive winter.

💡

An adaptation must match the habitat. If the environment changes too fast, animals with fixed adaptations may struggle to survive.
