Habitat of This Animal:
A:Forest along the valley - A2:Forest along the mountain streams
In Tokunoshima Island, abundant rainwater carved the ground, forming many rows of ridges and valleys. Plants adapting to the flowing and drying up of water grow in the harsh environment, where water swells and depletes every time rain falls. The waterfront is also a habitat for many creatures, including endemic species, with frogs and dragonflies breeding.
