Two-toed Amphiuma

• Its four legs are vestigial and have only two toes each: they are so tiny as to be invisible at a distance, and the animal moves by wriggling like an eel.
• The female coils around her clutch and stays with it for five months without feeding, protecting it from predators until it hatches.
• It has the largest red blood cells of any known vertebrate, a feature that has made it standard material in cytology laboratories and microscopy classes.
