Over 750 sp of terrestrial snails were once describedfrom the Hawaiian Islands. Sadly it is estimated thatover 90 % of this diversity has been lost. Habitatdestruction by introducing predatory speciesdepredate Hawaiis native snails.

Zebra mussels: native to freshwater lakes of southeast Russia. Spread to great lakes ofCanada and US in 1700s. Most likely made their way from home by travelling in ballastwater taken on by cargo ship. They compete with native sp and clog water treatmentfacilities and power plant cooling system.
