  1. Structural and Behavioral Adaptations Predators and Prey

  2. 1. Acute senses that are used to locate and identify prey items (e.g. heat-sensing pits of rattlesnakes, and chemical sensors of herbivorous insects). Predator Adaptations: Rattle snakes can sense heat through the pits in their heads.

  3. Insects have chemical sensors on there antennae.

  4. 2. Structures such as claws, teeth, fangs, stingers, and poisons that function to catch, subdue, or chew they prey item. Scorpions can kill prey with the stinger located on the last segment

  5. Teeth and claws can make short work of this Water Buffalo

  6. This Alligator can sit and wait for prey to come to close. Camouflage can work both ways! This alligator can sit and wait for prey to come to close. Camouflage can work both ways!

  7. Animal defenses against predators include hiding, escaping and physical or chemical defense. Other forms of defense involving adaptive coloration have evolved repeatedly among animals. They may also produce crypticcoloration (coloration making prey difficult to spot against its surroundings) is common and only requires the animal to remain still to avoid detection. Some use deceptive marking such as large, fake eyes can startle predators, allowing prey to escape, or cause predators to strike a non-vital area. Some mechanical and chemical defenses actively discourage predators (e.g. porcupine quills and skunk spray). Some insects acquire chemical defense passively by accumulating toxins from plants they eat; these make them distasteful to predators. Prey Adaptations:

  8. Eyes set out on the sides of the head, and big ears help this rabbit detect predators.

  9. There is a lizard hiding on this tree. Can you see it?

  10. When this Io moth is threatened it pulls back its upper wing revealing these "Eyes" which startle the predator long enough for the moth to escape.

  11. Symbiosis is a form of interaction in which two organisms maintain a close association. Mutualism Commensalism Parasitism Symbiosis

  12. Mutualism Pseudomyrmex Ants attack a Katydid placed on an Acacia Plant
