Named for the diamond-shaped patterns on its carapace, both the patterning and coloration vary greatly from turtle to turtle within this species. Diamondbacks exclusively inhabit coastal areas with brackish water. They are strong swimmers with webbed feet and thick, muscular legs that aid their navigation through coves, tidal marshes, and inlets subject to currents and tidal surges.
In recent years, Diamondbacks have been documented near Island Pond, also known as Oyster Pond, a body of water that has been brackish since it was breached by the 1938 Hurricane, restored as a fresh water pond, and breached again by another hurricane in the 1940s.
