The  marbled eel , also known as the  giant mottled eel ,  Anguilla marmorata , is a species of tropical anguillid  eel  that is found in  adjacent freshwater habitats Vietnam.

Like other anguillid eels, this species is used as a source of food in some regions.  Some restaurants buy live eels

 

Similar to other anguillids, the marbled eel is cylindrical with small, well-developed pectoral fins and a protruding lower jaw. The eel has thick, fleshy lips. The eel has dorsal and anal fins that are continuous around the tail, with the origin of the dorsal-fin origin between the pectoral fins and anus. It has small, oval-shaped scales that are embedded in the skin.

 

Unlike some other anguillid species, the marbled eel has a mottled color. The adult eels are yellow with a greenish-brown to black marbling on their back and a white belly. The young elvers have less visible marbling and are grayish to yellow.The dorsal fin of the marbled eel is closer to the gillopening than to the anus, more anterior than other species of  Anguilla .Like all anguillid eels, it does not have pelvic fins. The head is rounded and the snout is depressed. Its teeth are small and in bands. It has a total of 100 to 110 vertebrae.

 

It can grow up to 2 meters (6.6 ft) for females and 1.5 meters (4.9 ft) for males and can weigh up to 20.5 kilograms (45 lb), which is larger than most other species of anguillid eels. The marbled eel can live up to about 40 years.

Ecology and behaviour

The adults of this species are demersal, living on the bottom of fresh to brackish waters, in rivers, lakes, and tributaries. This species and all anguillid eels are catadromous, migrating sometimes long distances out into the open ocean to spawning over deep water.   A spawning area of this species is known to be west of the Mariana Islands in an area of the North Equatorial Current in the western North Pacific, but other spawning areas are thought to exist in the western South Pacific and Indian Ocean.

Marbled eels spend their adult lives in freshwater or estuarine habitats, and migrate to the ocean to reproduce. When the eggs hatch, the leptocephali drift in ocean currents for months until they reach estuaries as glass eels where they migrate upstream into freshwater as elvers. Then, after about 8 to 20 years in brackish or freshwater, the yellow eels grow up into silver eels (mature eels), and they return back to the ocean for reproduction.

The marbled eel is carnivorous, but harmless, with a wide ranging diet, eating shrimp, crabs, bony fish, and frogs. It is nocturnal, so it is active at night.
