Trap Door Snail

Trap door snails carry an operculum that seals the shell opening completely watertight when threatened — a hard shutdown that makes them tough enough to survive both aquariums and outdoor ponds through real temperature swings. Unlike most freshwater snails they give birth to fully-formed young rather than laying eggs, so no surprise egg clutches to deal with either.
