Chinese Mystery Snail

Cipangopaludina chinensis

Classification

The Chinese mystery snail, black snail, or trapdoor snail (Margarya chinensis), is a large freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Viviparidae. The name "trapdoor snail" refers the operculum, an oval corneous plate that most snails in this clade possess. When the soft parts of the snail are fully retracted, the operculum seals the aperture of the shell, providing some protection against drying out and predation.
