Heron with a Sargasso Eel - Drayton Fen

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. ... Eels hunt at night, feeding on crustaceans, small insects and other fish.
