Box and Water Turtles (Emydidae)

 

Box and Water Turtles (Emydidae)

The largest family of turtles worldwide, the Emydidae family, is represented in Maryland by thirteen species of turtle. With such diversity comes a variety of body types and habitat choices. Usually, the carapace is not highly domed, but there are a few species with high arches to their shells. Many species have a plastron that hinges, allowing for complete or partial closure. Several are almost completely aquatic while others are primarily terrestrial. The name Emydidae comes from the Greek "emys", meaning "freshwater terrapin", but some of our turtles will also use brackish water.​​
