ANIMAL ADAPTATIONS Physical and Behavioural Explained

ANIMAL ADAPTATIONS �All organisms have adaptations that help them survive and thrive. Some adaptations are physical. �Physical adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioural. �Behavioural adaptations are things organisms do to survive. For example, bird calls and migration are behavioural adaptations.

ANIMAL ADAPTATIONS �Group of Behavioural Adaptations �Instinctive � Happen naturally and are not learned. � Ducklings following their mother �Learned Behaviour � Behaviour must be taught � Dogs learning to roll over to earn treats Russian dogs on the subway

ANIMAL ADAPTATIONS �Types of Behavioural Adaptations Whales migrating �Migration � Whales that swim from the Antarctic to warmer waters to reproduce. �Camouflage � The chameleon that changes its colours to fit in its environment �Hibernation � Bears that sleep during the winter when food is very scarce �Mimicry � Stick insects

ANIMAL ADAPTATIONS Giraffes eating � Physical Adaptations � Earthworm � Each segment on an earthworm’s body has a number of bristly hairs, called setae(sometimes written as chaetae). These hairs provide some grip to help the earthworm move through the soil. � An earthworm has a streamlined body with no antennae or fins or arms or legs! This streamlined shape is an adaptation to living in narrow burrows underground and the need to move easily through the soil. � An earthworm has circular muscles that surround each body segment. It also has longitudinal muscles that run the length of its body. These two groups of muscles work together to help the earthworm move. � In order to get food into its mouth, an earthworm pushes its pharynx out of its mouth to grasp hold of its food. It then pulls the food back into its mouth and wets it with saliva.

Student Task � 1) Choose two animals of your choice and do the following on each of the two animals. a) Two describe organisers on their physical adaptations. b) Two describe organisers on their behavioural adaptations. 2) Do a compare and contrast graphic organiser on your two chosen animals.
