The Rainforest Let’s find out about the rainforest. What lives there?
Layers of the Rainforest EMERGENT LAYER The tallest trees are the emergents, towering as much as 200 feet above the forest floor with trunks that measure up to 16 feet around. Most of these trees are broad-leaved, hardwood evergreens. Sunlight is plentiful up here. Animals found are eagles, monkeys, bats and butterflies.
Layers of the Rainforest CANOPY LAYER This is the primary layer of the forest and forms a roof over the two remaining layers. Most canopy trees have smooth, oval leaves that come to a point. It's a maze of leaves and branches. Many animals live in this area since food is abundant. Those animals include: snakes, toucans and treefrogs.
Layers of the Rainforest UNDERSTORY LAYER Little sunshine reaches this area so the plants have to grow larger leaves to reach the sunlight. The plants in this area seldom grow to 12 feet. Many animals live here including jaguars, red-eyed tree frogs and leopards. There is a large concentration of insects here.
Layers of the Rainforest FOREST FLOOR It's very dark down here. Almost no plants grow in this area, as a result. Since hardly any sun reaches the forest floor things begin to decay quickly. A leaf that might take one year to decompose in a regular climate will disappear in 6 weeks. Giant anteaters live in this layer.

Animals of the Rainforest Poison-arrow frog Macaws Sloth Toucan Spider Monkey
Poison-arrow frogs are social frogs found in Central and South America. They are known by their bright colors which warn other animals that they are poisonous. Its poison is one of the most powerful known and can cause paralysis or death. It is so potent that one millionth of an ounce can kill a dog and an amount smaller than a grain of salt can kill a human. One frog carries enough poison to kill about 100 people. Native hunters use it on the tips of their arrows which is how the frog got its name.
Sloths are extremely slow-moving mammals found in the rainforest canopies of Central and South America. There are two species of sloths:two-toed and three-toed. Most sloths are about the size of a small dog and they have short, flat flat heads. Their hair is grayish brown but, at times they look grey-green in color because they move so slowly that tiny camouflaging algae grow all over their coats.
Macaws are the largest of all parrots. There are 16 different species of macaws and they range in size from a little over three feet to one foot. They have beautiful, graceful, tails that are as long or longer than their bodies. They also have long, pointed wings that enable them to fly swiftly.
Bromeliads are related to the pineapple family. Their thick, waxy leaves form a bowl shape in the centre for catching rainwater. Some bromeliads can hold several gallons of water and are miniature ecosystems in themselves providing homes for several creatures including frogs and their tadpoles, salamanders, snails, beetles and mosquito larvae. Those that die decompose and furnish the plant with nutrients. One bromeliad was found to contain several small beetles, crane flies, earwigs, a frog, a cockroach, spiders, fly larvae, a millipede, a scorpion, woodlice and an earthworm!
