About 100 species of land snails have been found in Ogasawara so far and new species continue to be discovered. More than 90 percent of the species of land snails living in Ogasawara are endemic to Ogasawara only. Of particular interest is the genus Mandarina mandarina. Each species in this genus feed on different things in different places and they inhabit slightly different environments. This variety in living style attributes to their different shapes.

Dry scrub brush grows throughout Anijima and Higashi-daira on Chichijima. The dry scrub is an integral part of the unique ecosystem with the many endemic species of the Ogasawara Islands. This indigenous species is similar to the evergreen broadleaf species in the forests of Okinawa, Japan, and Southeast Asia so experts assume that this species adapted to the dry weather after moving to the Ogasawara Islands.
