A preliminary checklist of the aquatic and terrestrial mollusks of the middle Snake River sub-basin

Call Number:

Abstract:

The freshwater mollusk fauna as presently understood comprises thirty native and two introduced snail species, and there are at least three additional taxa of non-native snails which inhabit thermal plumes in warmwater aquaculture outfalls. Seventeen native and a single introduced species of Bivalvia (clams) and nine living species of landsnails have been identified from the sub-basin. Several new regional and state records are presented. Mollusk species which are expected to occur but have not yet been verified from the Middle Snake River sub-basin are cited. Half of the eighteen native aquatic species which characteristically require cold, fastwater habitats or sediment sites in free-flowing reaches are presently either proposed for listing or are candidate endangered or threatened species and several others are declining. This is a working checklist to which there will undoubtedly be additions of both terrestrial and aquatic mollusks.
