Science: Adaptations for escaping from predators

  1. Living in groups
  2. Moving quickly from predators
  3. Hiding
  4. Defending themselves
  5. Appearing bigger and fiercer when threatened(camouflage)
  6. Warning colours or patterns(used to warn predators about bad-tasting or poisonous prey)
  7. Taking the appearance of others(camouflage)
-------------------
Living in groups(eg): elephants.

Purpose: It enhances survival of the plant-eaters, and they help one another to look out for predators

Moving quickly from predators(eg): Antelope

Purpose: It allows them to move quickly from predators

(Extra: A squid can force out a jet of water to help it swim away quickly)

Hiding(eg): Tortoises

Purpose: To hide from predators because they cannot move quickly enough

Defending themselves(eg): Porcupine

Purpose: To defend themselves. They have structural adaptations like quills, horns and armour-like shells.

Appearing bigger and fiercer when threatened: Puffer fish

Purpose: To scare predators. They can make themselves look bigger and more dangerous when threatened by swelling up using water or air.

(Extra: Some puffer fish are spiny and dangerous)
