American eels spawn in the Sargasso Sea, then currents carry them to various rivers in North America. The larvae are shaped like a willow leaf. Juvenile (yellow eels) colouration varies from yellow to green or olive-brown on the belly and dark on the back. Adults (silver eels) are grey with a white or cream-coloured belly. Adult females may reach up to 1 metre in length and males are smaller, at less than 0.4 metres.
Where to find this species
American Eels can absorb oxygen through their skin as well as through their gills, allowing them to travel briefly over wet grass or mud.
