There are more than 500 fish species known as eels. They are slender, elongated, and usually scaleless, with long dorsal and anal fi ns that are continuous around the tail tip. Eels are found in all seas, from coastal regions to the mid-depths. Freshwater eels are active, predatory fish with small embedded scales. They grow to maturity in freshwater and return to the sea, where they spawn and die. The transparent young drift to the coast and make their way upstream. Freshwater eels, considered valuable food fish, include species ranging from 4 in (10 cm) to about 111⁄2 ft (3.5 m) long.
