The forests of the Amami Islands primarily consist of subtropical evergreen and broadleaf trees, such as the itajii and flying spider monkey tree ferns. The islands also shelter many endemic species of lilies, orchids and azaleas, including Tokunoshima ebine.
The area is incredibly biodiverse, home to creatures such as the Amami rabbit, Amami spiny rat, Amami Ishikawa's frog, Amami thrush, and the banded ground gecko. The seas around the islands are filled with around 220 species of coral, and attract a variety of marine life.
