    Impacts:
    Predation: Mandarina snail species have suffered serious destruction of habitat due to cultivating land for crops since 100 years ago (Kurozumi 1988; Tomiyama 1994 in Satoshi 2003). However, the most serious problem is predation by introduced species. For example, the predatory flatworm, Platydemus manokwari, other predatory flatworms and the carnivorous land snail E. rosea (Kawakatsu et al. 1999, Ohkouchi et al. 1999, Tomiyama 2002, in Satoshi 2003). The effect of these introduced predators on native land snail fauna is so serious that they may rapidly cause the extinction of many of the native land snails in the Ogasawaras.
