Animal Adaptations

“Surface Area to Volume ratio”
Key term to use: “Surface Area to Volume ratio”

Types of Adaptation ‘Any feature or behaviour that helps an organism survive in its environment’ is an adaptation. It also refers to the ability of living things to adjust to different conditions within their environments. Structural adaptation Camouflage Mimicry Behaviour adaptations Migration Hibernation

Structural adaptations
A structural adaptation involves some part of an animal's body… A structural adaptation involves some part of an animal's body, such as the size or shape of the teeth, the animal's body covering, or the way the animal moves. Teeth - since different animals eat different things, they don't all have the same kind of teeth Body coverings - Hair, scales, spines, and feathers grow from the skin. All of these parts help animals survive in their environments. Movement - animals find food by moving from place to place

Camouflage Coloration and protective resemblance allow an animal to blend into its environment. Another word for this might be camouflage. Their camouflage makes it hard for enemies to single out individuals.

“Look at me – I’m dangerous!”

“Don’t look at me...”

“…please!!”

What is it??
13
Mimicry Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous. Coral snake (left) very poinsonous & Milk snake (right)

Behaviour adaptations
Behaviour adaptations include activities that help an animal survive. Behaviour adaptations can be learned or instinctive. Social behaviour Behaviour for protection Behavior adaptations include activities that help an animal survive. Behavior adaptations can be learned or instinctive. (a behavior an animal is born with). Social behavior - some animals live by themselves, while other live in groups. Behavior for protection - An animal's behavior sometimes helps to protect the animal. For instance the opossum plays dead. A rabbit freezes when it thinks it has been seen.
15
Migration Animals migrate for different reasons.
This is when behavioural adaptation that involves an animal or group of animals moving from one region to another and then back again. Animals migrate for different reasons. better climate better food safe place to live safe place to raise young go back to the place they were born. Migration-is the behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again. Animals migrate for different reasons. The reasons are as follows. better climate better food safe place to live safe place to raise young go back to the place they were born.
16
Hibernation This is deep sleep in which animal’s body temp droops, body activities are slowed to conserve energy. E.g. Bats, squirrels & bears. Hibernation- is a deep sleep in which an animal's body temperature drops to about the temperature of the environment. Body activities, such as heartbeat and breathing are slowed causing the animal to need very little food. Animals that hibernate are bats woodchucks snakes bears. During the hibernation the animals live off of the fat that is stored in their body.
