We love them anyway. Glochidia are unable to swim or crawl. Their only behavior is to close at an opportune moment when they come into contact with the gills or fins of the host fish. The tissue of the fish reacts by forming a capsule or cyst around the glochidium.
Mussels are host-specific.
If glochidia attach to the wrong species the cysts are soon lost. This glochidium of Simpsonais ambigua is on the wrong host and is about to fall off. Dr. Dick Neves and his students at Virginia Tech have developed methods for rearing juveniles. The salamander mussel, Simpsonais ambigua transforms on mudpuppy salamanders rather than fish.
