About Terrapins

The diamond-backed terrapin is the only turtle species to live exclusively in brackish water. Because of their limited distribution and unique life history, the Texas subspecies (Malaclemys terrapin littoralis) may be an important indicator species for Texas bays. Various sources of mortality have been identified including habitat loss, crab trap bycatch, power plant intakes, vehicular impacts, and boating impacts. Little information has been gathered on the numbers or health of local Texas populations.

Texas diamond-backed terrapin research by the Environmental Institute of Houston is currently taking place in marsh areas along the upper and central Texas coast. Help the Environmental Institute of Houston continue to research and protect the Texas diamond-backed terrapin by symbolically adopting a terrapin!
