Boonea bisuturalis
Boonea bisuturalis (also known as the three-toothed odostome or the two-groove odostome) is a species of small sea snail, a pyramidellid gastropod mollusk or micromollusk in the family Pyramidellidae, the pyrams and their allies. The species is one of eleven known species within the Boonea genus of gastropods.
This species is ectoparasitic (an external parasite) on various bivalves and other gastropods. It is notorious as a pest on oyster beds. Its preferred hosts are the common periwinkle Littorina littorea, the mud snail Tritia obsoleta and the eastern oyster Crassostrea virginica
