Introduction

Adaptation is a condition where animals naturally modified or change their behavior or;

their physical characters to adjust with the nature surrounding

5

Types of adaptation

Adaptations can be divided into 2 differenttypes:• Animal’s action (behavioral)• Physical characteristic of the animal

6

The arts of adaptation

• Movements and locomotion• Feeding behavior• Gas exchange• Body temperature regulation• Camouflage• Mimicry• Migration• Hibernation• Predator-prey

7

Movement and locomotion 1

a. Bird (flight):– Wing (to fly & strong)– Bone– Aerodynamic structure– Lay egg (reduce weight)– Feather /plumul (not easily wet)

8

Movement and locomotion

Fish (swim)• Slender body• Fin and caudal fin

• Dessert snake (hot surface)

9

Feeding behavior 1

• Animals are adapted to what they eat in their natural habitat

• Their behavior is adapted to the ecosystem they belongs to

10

Feeding behavior 2

• Herbivores• Carnivores• Omnivores• Insectivores• Frugivores

11

Feeding behavior 3

• Mouth part• Jaws/dental• Digestion systems

12

Camouflage

• Colour or shape in animal’s body covering help it blend with its environment

13

Mimicry

Harmless animals look like harmful

14

Hibernation

• Conserve energy → deep sleep• Body temperature drop, heart beat slow• Before winter, hibernate animals (bear, skunk,

chipmunk, et) will consume a lot of food and stored as fat.

• Some animal stay in the burrow and some stay in the mud and they become dormant.

Why adaptation is important?

1. Adaptation allows animals to adjust themselves and survive in their natural habitat

2. Adaptation help animal to maximize their species survival in their environmental habitat

3. Adaptation assist animals to move, survive from predator, catch prey or find food, find mate and eat

4. Successful adaptation allow animals to live and survive long enough to reproduce and produce offspring
