Physical and BehavioralPhysical and Behavioral

Animals adapt in many ways. There are two types of adaptations. Physical and Behavioral. Animals adapt in many ways. There are two types of adaptations. Physical and Behavioral.

Physical is how an animal looks. It is it’s physical features such as beaks, tails, claws, and Physical is how an animal looks. It is it’s physical features such as beaks, tails, claws, and much more. A skunk has a physical adaptation that protects it from harm. Do you know what much more.

Behavioral is how an animal behaves. If your teacher says you had great behavior, he or she Behavioral is how an animal behaves. If your teacher says you had great behavior, he or she means you acted very well. means you acted very well.

We will explore some examples of physical and behavioral adaptations now. We will explore some examples of physical and behavioral adaptations now.

Physical AdaptationsPhysical Adaptations

Physical adaptations may be how many fingers an animal has, how thick its fur it, or how it changes to attract a mate.

Physical adaptations do not form overnight. They can take hundreds of years to transform and usually change because of the climate.

With today’s constantly changing environment, animals habitats or living places are changing.

An animal has to readjust to that new surrounding or climate. If they can’t the animal dies.

You will learn more about how climate changes and then with time it forces animals to change and adapt later in this lesson.

BiomesBiomesThere are six major types of biomes where all There are six major types of biomes where all

animals could live and “adapt” to in order to animals could live and “adapt” to in order to survive. survive.

FreshwaterFreshwater --Includes wetlands, streams and rivers, ponds and lakes. Animals that live here require low salt intake. Temperature of the water changes drastically with the seasons.

(fish such as catfish, shrimp. ducks, turtles, snakes, birds)

MarineMarine – – Cover about 75% of Earth’s surface. Marine includes oceans, estuaries, and coral reef. High salt concentrations.

(mammals such as dolphins and whales, crabs, worms, octopuses)

DesertDesert – –Cover about 20% of Earth’s surface. Few animals live in very hot deserts because the desert offers little protections from the hot sun. Semi-arid, coastal, coastal, and cold deserts contain more animals.

(rabbits, skunks, owls, snakes, jack rabbits, mice, coyotes, and badgers)

Biomes- ContinuedBiomes- Continued

Forest (Taiga)Forest (Taiga)- There are three types. tropical, temperate, and boreal. Tropical-near equator(birds, bats, small mammals.)

Temperate-eastern North America, northeastern Asia, and western and central Europe ((squirrels, rabbits, skunks, birds, deer, mountain lion, bobcat, timber wolf, fox, and black bear.))

Boreal-short, moist summers, long cold winters(hawks, small mammals, bats, lynx, bears)

GrasslandGrassland– Two types savannah and temperate (includes prairies). Africa, India, South America.

(Savannah-giraffes, zebras, buffaloes, kangaroos, mice, moles, gophers, ground squirrels, snakes, worms, termites, beetles, lions, leopards, hyenas, and elephants.))

(Temperate- gazelles, zebras, rhinoceroses, wild horses, lions, wolves, prairie dogs, jack rabbits, deer, mice, coyotes, foxes, skunks, badgers, blackbirds, quails, sparrows, hawks, owls, snakes, grasshoppers, and spiders)

Biomes- ContinuedBiomes- Continued

Tundra- Two types; Arctic and Alpine. Arctic is coldest of all biomes. Tundra means “treeless.” characterized by short growing seasons and reproduction seasons.

Arctic- Northern Hemisphere, North Pole (lemmings, caribou, arctic hares, squirrels, arctic foxes, wolves, polar bears,

snow buntings, falcons, loons, terns, snow birds, mosquitoes, flies, moths, grasshoppers, black flies, salmon, and trout)

Alpine- very high mountaintops of Alaska and Washington. (marmots, mountain goats, sheep, elk, beetles, grasshoppers, butterflies)
