<P> The understory or understorey layer lies between the canopy and the forest floor . It is home to a number of birds, snakes and lizards, as well as predators such as jaguars, boa constrictors and leopards . The leaves are much larger at this level and insect life is abundant . Many seedlings that will grow to the canopy level are present in the understory . Only about 5% of the sunlight shining on the rainforest canopy reaches the understory . This layer can be called a shrub layer, although the shrub layer may also be considered a separate layer . </P> <P> The forest floor, the bottom-most layer, receives only 2% of the sunlight . Only plants adapted to low light can grow in this region . Away from riverbanks, swamps and clearings, where dense undergrowth is found, the forest floor is relatively clear of vegetation because of the low sunlight penetration . It also contains decaying plant and animal matter, which disappears quickly, because the warm, humid conditions promote rapid decay . Many forms of fungi growing here help decay the animal and plant waste . </P> <P> More than half of the world's species of plants and animals are found in the rainforest . Rainforests support a very broad array of fauna, including mammals, reptiles, birds and invertebrates . Mammals may include primates, felids and other families . Reptiles include snakes, turtles, chameleons and other families; while birds include such families as vangidae and Cuculidae . Dozens of families of invertebrates are found in rainforests . Fungi are also very common in rainforest areas as they can feed on the decomposing remains of plants and animals . Many rainforest species are rapidly disappearing due to deforestation, habitat loss and pollution of the atmosphere . </P> <Table> <Tr> <Td> </Td> <Td> This section needs expansion .
