ADAPTATIONS

STRUCTURAL ADAPTATIONS

Allows animal to glide through air “Flying Squirrel” Skin forms “wings” Allows animal to glide through air Animal can leap from tree to tree or to ground quickly Avoid predators Increasing safety decreases risk of injury

“Indian Blanket” Bright color toward center Attracts insects Promotes pollination Increasing reproduction chances

PHYSIOLOGICAL ADAPTATIONS

“Flat Rock Scorpions” Produce a poison Protection from predators Additional Adaptations Very flat – fit into rock crevices Active alte in day

“Camel” Fat stores in hump Body will slowly metabolize (burn) for energy when food is not available Additional Adaptations Double set of eyelashes Air tight closure of nostrils Football shaped blood cells

BEHAVORIAL ADAPTATIONS

Lions Hunt in groups Increase chance of success Reduce amount of energy spent by an individual while hunting

“Tortoise” Resting in a hallow tree Provides shelter Protection from predators Protection from the elements – weather, sun

Now Its Your Turn Indicate what type of adaptation is demonstrated by organisms in the following slides Explain the benefit or advantage it provides the organism

Jack Rabbit Structural Large ears Helps maintain body temperature by allowing blood to be cooled Intensify sound to better hear predators

Dandelion Seeds Physiological Structural Produces large number of seeds Increases the number of offspring Increases the species chance of survival Structural Allows seeds to be dispersed (spread out) easily by the wind Decreases competition in one area by spreading out the population

Meerkats Behavioral Live in large groups (colonies) Have members on guard duty All members help raise the offspring Hunt in groups and teach youngsters how to find food All help reduce risk of predators and competitors Increases chances of survival

Bird Skulls with Bills Structural Designed to allow the birds access to a particular type of food Decreases competition for resources

Lockwood Alligator Behavioral Remains motionless with mouth open Helps to cool its body and regulate its body temperature

Venus Fly Traps Physiological Structural Obtains necessary nitrogen from insects, instead of the soil Can live in nitrogen poor soils Produces enzymes to digest insects slowly Structural Sensitive “trigger hairs” Rapidly snap shut to capture prey

King Vulture Physiological Structural Larger olfactory nerve (smell) then any other bird Can smell food easier, makes food easier to find Structural No feathers on head To avoid blood from carrion (food) sticking to head Shape of beak and talons (claws) Tear off pieces of carrion

Olympic Runner Behavioral Physiological Training and Nutrition routines Physiological Release of adrenalin a hormone in the body Increases heart rate, blood flow to the muscles and lungs, blood pressure, alertness Sweating to help maintain body temperature Cools the body
