American crocodile. Like many crocodilians, this species has suffered from commercial overexploitation and habitat destruction.
Black swamp snake. Loss of Carolina bay wetlands has reduced habitat for black swamp snakes and other semi-aquatic reptile species that are restricted primarily to seasonal wetlands.
Habitat loss and degradation are primary threats to both amphibian and reptile populations. Conversion of wetlands, especially seasonal wetlands, and surrounding terrestrial habitat to agricultural (illustrated here) and other uses have resulted in wetland losses exceeding 80% in many states.
Eastern box turtle. The pet trade appears especially hazardous for some turtle species, such as the eastern box turtle.
Snapping turtle eggs and hatchlings. Most contaminant studies on reptiles have been conducted on snapping turtles and alligators, in which sex reversal and abnormal gonads have been noted.
Southern hognose snake. This species has not been recorded from regions of its historic range in Alabama and Mississippi for more than 18 years. Its disappearance is somewhat mysterious, as the reasons for its decline are not well understood.
Sand monitor (Varanus gouldi). Although sand monitors (genus Varanus, which includes the world's largest lizards) appear to be thriving in many parts of their natural habitats in Australia, other species of the genus in Asia, Africa, and the East Indies are threatened by extensive habitat destruction. |
