               TROPICAL RAIN FOREST
               •  The tropical rainforests are dense warm and wet. There plenty of vegetation and various
                   types of animals are found.
               •  To avoid competition for food, the animals confine themselves to different layers of the
                   forest.

               •  The different layers of the forest are-
                      Layers                  Flora                              Fauna
                 Emergent (top     Tall trees                  Eagles, monkey, bats, some insects

                 layer)
                 Canopy            Dense layer of trees        Sloths, snakes, lizards, insects and
                                                               birds(toucan)
                 Understory        Leafy herbaceous plants     Jaguars, frogs, leopards
                 Forest floor      Almost no vegetation        Anteaters, snakes, mice and insects.

               ADAPTIVE FEATURES OF ANIMALS LIVING IN TROPICAL RAINFOREST
               A.  LION-TAILED MACAQUE-
                                                                          DO YOU KNOW!
                   •  It spends most of its time on branches of trees
                                                                          The Lion-tailed Macaque is listed
                       and is adapted to grasp the branches with its
                                                                          as ‘Endangered’ in the IUCN Red
                       hands and long muscular tail. Such animals are
                                                                          List, with less than 4000
                       called arboreal animal.
                                                                          individuals left in the wild.
                   •  They feed on fruits, seeds, flowers, leaves and
                       some insects.
                   •  They have a characteristic mane around the face.
               B.  RED-EYED TREE FROG-

                       •  They have bright green body with pale-yellow           DO YOU KNOW!
                          stripes which helps in camouflaging with the leaf.     Red-eyed tree frogs have
                       •  Their feet have suction cups on the toes to stick to   three eyelids on each eye!
                          the trees.
                       •  Their eyes are red and bulging which scares away potential predators.
                       •  They are nocturnal animals-sleeps during the day time.
               C.  TOUCAN-

                   •  The toucan lives on the upper layers of trees.
                   •  They have big, strong and sharp beak to squash many kinds of nuts berries.
