Red-eared slider (Trachemys scripta elegans) Red-eared Terrapins are almost entirely aquatic but leave the water to bask in the sun and lay eggs. They were originally imported to be sold as pets due to Ninja Turtle cartoon characters, as small youngsters that can be kept easily in a fish tank. However, as they grow to adult size many owners are unable to cope with their needs and they either escape or are illegally released into local ponds, where they now can be found. They will hibernate in the colder months except in very mild periods. At least three in one pond in Bury. Increasing.
