Adaptations

Adaptations Characteristics that give an organism or a species a better chance of survival.

Reasons for adaptations To suit their habitat For protection For finding mates For feeding For movement

Types of Adaptations Structural – physical characteristics Size, shape, coloration Feet, eyes, bills, skin Gills Hollow bones Xylem

Types of Adaptations Behavioral – differing ways of reacting to the environment Nocturnal Migrating Burrowing Hibernating

Type of Adaptations Physiological – internal biochemical functions Snakes producing venom Maintaining temperature Spiders producing silk for webs

Which adaptation are these? Sharp teeth and claws for carnivores Flat teeth for grinding and chewing Moving in large groups; it helps protect the members of the group from predators. The thick fur coat of an arctic fox helps protect it against the cold weather. Camouflage Mimicry

Habitat: Dry inland Australia, including deserts and grasslands Adaptations: It is able to go without drinking as long as green grass is available and it adapts well to drought. They can hop as fast as 40 mph (64 km).  They use this as their first line of defense.  Kangaroos have a tendon in the leg which acts like a rubber band, conserving energy as the animal moves. The tail serves as a balance when the animal leaps and as a prop when it stands.

Habitat: Frigid seas Adaptations: Black and white colors. These colors help camouflage them. Their blowhole is at the top of their head. This enables them to come up and breathe more easily. Blubber keeps them warm in the frigid seas. Orcas are the fastest mammals in the sea. They can go up to 34 mph. Their speed helps them catch their prey.

Habitat: Wet, humid and hot jungles as well as icy cold forests Adaptations: A tiger's hind limbs are longer than the forelimbs, which aids them in jumping. The forelimbs and shoulders are well-muscled, and the forelegs can twist inward, enabling the tiger to grab and hold large prey. The underside of the paws have soft pads which allow tigers to quietly stalk their prey.

Habitat: Tropical secondary forest Adaptations: Opposable thumb enables manipulation of objects; big toe also opposable for grasping. Large and powerful arms used to break stalks or uproot vegetation while foraging. High intelligence probably an adaptation for finding scarce or isolated fruit plants in the rain forest.

Habitat: Dry deserts Adaptations: The spines serve a number of purposes in addition to protection from hungry and thirsty animals. They provide shade, serve as a windbreak to prevent dehydration from dry winds, and help trap warm air close to the plant. The root systems of cacti are very close to the surface of the soil, making it possible for them to take advantage of the slightest rain shower.
