Structural Adaptation Example: QUILLS on a porcupine (defense)
Structural Adaptation Example: prehensile tail on a spider monkey (climbing)

Structural Adaptations Definition • Physical feature that helps and organism survive • Body part that gives an advantage Example: prehensile tail on a spider monkey (climbing) Example: thick fur on an arctic fox (warmth) Example: QUILLS on a porcupine (defense)
Behavioral Adaptations Definition • Things that organisms DO (voluntary) • A Way an Organism purposely acts to survive
Behavioral Adaptation Example: fish swim in schools (protection)
Behavioral Adaptation Example: bird calls (attract mates, defense)

Behavioral Adaptations Definition • Things that organisms DO (voluntary) • A Way an Organism purposely acts to survive Example: fish swim in schools (protection) Example: bird calls (attract mates, defense) Example: squirrels bury nuts (resource for winter)
Physiological Adaptations Definition • Chemical or cellular activity to help organism survive in its environment • automatic / involuntary Example: shedding winter coat (stay cool in hot weather) Example: sweating (stay cool)
Physiological Adaptation Example: shedding winter coat (stay cool in hot weather)
Physiological Adaptation Example: sweating (stay cool)
Physiological Adaptation Example: adrenaline is pumped into the bloodstream when you get scared or surprised (heart speeds up – you’re ready to run)
