Characteristics of Plants and Animals

One type of plant often found in a rainforest is an epiphyte. Epiphytes are plants that live on the surface of other plants, especially the trunks and branches.

Tropical rainforests are home to half the plant and animal species on Earth.

A common characteristic found among mammals, birds, reptiles and amphibians, is an adaptation to living in trees.

One example is New World monkeys that have prehensile tails that curl around branches allowing the monkey to hold onto the tree with its tail! Other animals are brightly colored, sharply patterned, have loud vocalizations, and like to eat lots of fruit.

There is so much food available up in the trees there that some animals never go down to explore the forest floor!
