Both have similar lifecycles but different distributions in freshwater systems except in Iceland, where both (and hybrids of both species) can be found. The American Eel is the only representative of its genus (or group of related species) in North America, but it does have a close relative which shares the same spawning area: the European Eel. In Indigenous languages, like Mi’kmaq, it is known as k’at or g’at, the Algonquins call it pimzi or pimizi, in Ojibwe bimizi, in Cree Kinebikoinkosew and the Seneca call it goda:noh. It is known by a variety of names in Canada, including: the Atlantic Eel, the Common Eel, the Silver Eel, the Yellow Eel, the Bronze Eel and Easgann in Irish Gaelic. Large females turn dark grey or silver when they mature. Females are lighter in colour than males. Adult eels vary in coloration, from olive green and brown to greenish-yellow, with a light gray or white belly. With its small pectoral fins right behind its gills, absence of pelvic fins, long dorsal and ventral fins and the thin coat of mucus on its tiny scales, the adult eel slightly resembles a slimy snake but are in fact true fish. Males tend to be smaller than females, reaching a size of about 0.4 m. It is a long, slender fish that can grow longer than one metre in length and 7.5 kilograms in weight. The American Eel can live as long as 50 years. It is born in saltwater and migrating to freshwater to grow and mature before returning to saltwater to spawn and die. But its life-cycle is exactly the reverse of salmon’s: the eel is a catadromous species. Like salmon, it lives both in freshwater and saltwater. The American Eel ( Anguilla rostrata) is a fascinating migratory fish with a very complex life cycle.
