Do eels hatch from eggs?
The females release their eggs, the males fertilise them, and the adults die after spawning. The eggs hatch into larvae that float to the surface and drift back towards New Zealand. They may take about 17 months to arrive. Over a decade (or more) later, adult eels head out to sea to spawn, and the cycle continues.
Where do all eels breed?
Eels have a complex lifecycle that begins far offshore in the Sargasso Sea where adults spawn. After eggs hatch, young eels drift inland with ocean currents into streams, rivers and lakes for over 3,700 miles. This journey may take many years.
