As in all other tropical forest areas the arboreal animals of the Indomalayan ecozone have evolved into a vast variety of strange forms. Many of these have developed from the arbrosaurs of the other realms. The tropical forests here support an extensive range of plants, and so there are many different kinds of insects and plant-living creatures found in the forest. They in turn become prey for a wide variety of carnivorous (such as insectivorous) animals.
