June 12 - Paramoeba perniciosa

This amoeba is responsible for causing disease in several species of crabs and lobster. It is a feared parasite amongst crab fishermen and Maryland foodies as epizootics can cause very high mortality of crabs such as blue crabs and gray crabs, by destroying their connective tissue.
