Tropical evergreen forests are found near the equator and known worldwide for the diversity of their flora and fauna. Animals living in these forests have adapted to a world with only two seasons: rainy and dry. Average temperatures remain relatively constant between 20 and 25 degrees Celsius (68 to 77 degrees Fahrenheit), and the sun shines for about 12 hours everyday throughout the year. Not all tropical evergreen forests are rainforests; some experience less rainfall. However, all of these forest ecosystems are characterized by an abundance of animal and plant life.
Most animals living in tropical evergreen forests live in the tree canopy, in part because very little sunlight reaches the forest floor. Chimpanzees, Golden Lion Tamarin, Slender Loris, Proboscis Monkeys, Orangutans, Silvery Gibbons and Sloths make their way through the treetops, while snakes like Wagler's Pit Vipers hide behind leaves. Birds like the predatory Harpy Eagle, the fruit-loving Jambu Fruit Dove and the Toco Toucan soar through the canopy as well.
Animals of all sizes walk the tropical evergreen forest floor. Animals as large as the African Forest Elephant, Bengal Tiger and Sumatran Rhinoceros share this unique ecosystem with animals as tiny as the Musky-Rat Kangaroo, the smallest member of the kangaroo species. Gorillas and deer are found in some of these forests as well.
Insects and arachnids abound in this ecosystem. Here, Bird Wing Butterflies grow to over one foot in length while Leaf-Cutter Ants work hard among the leaves. Worms, weevils, grasshoppers, katydids and hundreds of thousands of beetle species call these forests home.
