Behavioural Adaptations STRUCTURAL

CASE STUDY: Snake Adaptation Function (how does it help the animal? ) Bite and release during hunting (Hunting) During a strike the fangs pivot forward to gain contact with the desired target, usually a vole or a mouse. After a strike is made the snake instantly releases its fangs and waits for the animal to stop moving before attempting to swallow it. This bite and release ensures that a fighting animal will not injure the snake through a bite or a scratch. Though the mouse or vole may escape it will die soon afterward.

CASE STUDY: Shark Adaptations Function (how does it help the animal? ) Time of attack (Hunting) Great White Sharks usually attack a couple hours after sunset when visibility is poor. The sunlight spots preys at the surface of the water. Particles suspended in the water scatter light creating a veil which hides the shark. Place of attack (Hunting) Great White Sharks learn to hunt in locations with the highest chance of a successful prey capture.

Behavioural Adaptations often are used to achieve one of three goals: • Hunting- Obtaining food or water • Defenses/Protection • Reproduction Why do you think this is the case?

CASE STUDY: Eucalyptus Adaptation Function (how does it help the animal? ) Reproduction The eucalyptus tree releases seeds after there has been a fire. All the nutrients for the seeds to germinate are found in the ask bed, also known as the "ash bed effect". This gives the eucalyptus trees less competition from other plants who cannot survive after fire conditions meaning the young trees will have a better chance of survival.

CASE STUDY: Sunflowers Adaptations Function (how does it help the animal? ) Moves toward the sun Sunflower is notable for turning to face the Sun, a behavior known as heliotropism.
