Lecture Notes: Adaptation of Animals to Habitats

Introduction

• Theme: Exploration of how animals adapt to their habitats.
• Focus Animal: Octopus.

The Octopus

• Habitat: Underwater world.
• Physical Traits:
  • Eight arms for movement along seabed.
  • Covered in suckers that act as taste receptors (akin to having hundreds of tongues).
• Adaptation: Master of disguise, spineless, squeezes into tight spaces to hide.

Concept of Habitat

• A habitat provides creatures with:
  • Food
  • Shelter
  • Air
  • Water
• Interactions:
  • Plants provide shelter and food for herbivores.
  • Herbivores serve as prey for predators.
  • Interdependence in ecosystems.

  • Winter energy conservation through hibernation.

Closing Thoughts

• Consider other habitats and the animals and plants adapted to them.
