Diamondback terrapins (Malaclemys terrapin) occur in coastal habitats along the Atlantic and Gulf coasts of the United States and have experienced range-wide population declines due to habitat loss and entrapment in commercial and recreational crab pots. While physical barriers have been proposed such as bycatch reduction devices, their effectiveness is skewed towards the largest individuals. Diamondback terrapins are attracted to the same bait used to lure crabs, thus causing them to become entrapped. An ex-situ experiment observing terrapin entry behavior to crab pots was performed.
