3. Rainfall • rainfall is often more than 100 inches a year • The trees themselves give off water through the pores of their leaves (transpiration); it accounts for as much as half of the precipitation in the rain forest • With over 80 inches of rain per year, plants have made adaptations that helps them shed water off their leaves

6. Vampire Bat • Adaptations • Thumb claw that sticks out from the front of its wing to aid climbing around prey • Specialized infrared sensors on its nose used to perceive temperature • Front teeth specialized for cutting

7. Kinkajou • Adaptations • Sharp claws help them climb trees and their long tails help them hang from tree to tree (due to its grip) • Teeth are good for eating and ripping food found in the rainforest • Benefits from the environment by eating insects such as termites
