• An alteration or adjustment in structure or
habits, often hereditary, by which a
species individual improves its condition in
relation to its environment
Types of adaptation
• Structural- e.g. a snails shell ,to protect it
• Behavioral- e.g. a turtle going into its shell,
to get away from predators
• Physiological- e.g. a snake producing
venom, to kill its prey.
• Structural- A tiger's body is built for capturing and
killing large prey through stealth and sudden attack The
forelimbs and shoulders are well-muscled, and the
forelegs can twist inward, enabling the tiger to grab and
hold large prey.
• Behavioral- In the wild, tigers probably live about 15
years. Tigers in zoos have lived 16 to 18 years
• Physiological- The jaws are short and powerful, and
generally contain 30 teeth.
Incisor teeth help to grab hold of prey as well as pull
meat off bones
