Adaptations
Animal Traits• Different animals have
different shapes and sizes• They may even have different
body parts• Each feature is important to
the survival of the specific animal
• Things like body types are inherited from the animal’s parents
• Traits are body features that an animal inherits
• Are the features always physical things?
Behavioral Traits
• Instincts
• Migrating
• Hibernating
Instincts vs. Learned Behaviors• Instincts are behaviors
that animals are born to know how to do.
• Nest-making• Taking care of young• Defending oneself
• Learned behaviors are taught behaviors that are essential to the animal’s survival.
• These behaviors may also be learned through experience.
• Bears teach their cubs to hunt
• If an animal eats a bug that doesn’t taste good, he less likely to do it again.
Which type?Learned Behaviors Instincts
Bird Singing
Cub learning to hunt

Hibernate
• When animals enter a deep sleep in which life activities slow down
• Why do animals do this?• The animals cannot find
enough food to keep their bodies warm during the winter
• In the fall animals eat a lot of food to help them survive through the long winter
• Heartbeat slows• Body temperature drops• Breathing slows• Bats, chipmunk, bears
Migrate• When animals travel as a
group from one place to live in another
• Many birds fly south in the fall to spend the winter in warmer places
• Why do they migrate?• Gray whales, monarch
butterflies, geese, ducks, caribou
• Why doesn’t a small herd of caribou migrate?
Structural Adaptations
What are structural adaptations?
• Adaptations that an animal posses that helps him survive in its habitat.
• Reasons animals adapt– Food– Climate– Get oxygen– Protection from Predators– Raise its young
Camouflage
• A natural disguise some animals have to help them blend in with their surroundings
• Colors, patterns, shapes• Some animals that live in
the snow have white coat to provide camouflage
• Polar bears, arctic foxes, snowshoe rabbits, chameleon, frogs, fish, bugs
