Red-eared sliders (Trachemys scripta elegans) are the most popular pet turtles in the United States. This one in Carnegie Museum of Natural History’s Alcohol House has two heads. Due to extensive trading and people releasing their pets into the wild, red-eared sliders are listed as one of the world’s 100 most invasive species.
