Bivalves: Bivalvia - Conservation Status

species listed freshwater hundred

Habitat pollution and alteration are the greatest threat to freshwater bivalves, but the introduction of exotic species, such as zebra mussels, can also be disastrous. Nearly one hundred species of freshwater pearl mussels in Eastern North America are already extinct. Most of the remaining species are protected and officially listed by the government as either threatened or endangered. Over two hundred bivalve species are listed by the World Conservation Union (IUCN). Only eight, all giant clams, live in the ocean.
