Greater Siren   (Siren lacertina)
Category: Amphibians



These eel-like amphibians are one of the largest amphibians in North America. They are aquatic and can be found in streams, swamps, lakes, and rivers. Their front legs are so small that they can be hidden in their gills. They are nocturnal and mostly carnivorous, and like sharks, use a lateral line sense organ to detect prey.
