Glyptemys is a genus of turtles in the family Emydidae. It comprises two species, the bog turtle and wood turtle, both of which are endemic to North America. Until 2001, these turtles were considered members of the genus Clemmys, which currently has one member, the spotted turtle. Full grown, these turtles grow to between 8.9 and 20 cm (3.5 and 7.9 in). These turtles are semiaquatic, although this varies based on season.
