Enteric neuroplasticity in seawater-adapted European eel “(Anguilla anguilla)
European eels live most of their lives in freshwater until spawning migration to the Sargasso Sea. During seawater adaptation, eels modify their physiology, and their digestive system adapts to the new environment, drinking salt water to compensate for the continuous water loss. In that period, eels...

European eels live most of their lives in freshwater until spawning migration to the Sargasso Sea.
