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.

💡

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