Abstract. Freshwater pearl mussel is a wildlife crime priority, as illegal pearl fishing is decimating populations. People are often more familiar with the Swan Mussel Anodonta cygnea or the Duck Mussel Anodonta anatina, and most will never be fortunate enough to see this rare cousin. Human activity hits mussels hard: Of the 270 North American freshwater mussel species (top graph), 30 have gone extinct in the last 100 years, 95 have been listed as endangered or threatened, and a large proportion of the remaining species are considered vulnerable (middle pie chart).
