rice-paddy eel

Open encyclopedia reference

The rice-paddy eel (Pisodonophis boro; also known commonly as the Bengal's snake-eel, the estuary snake eel, or the snake eel) is an eel in the family Ophichthidae (worm-snake eels). It was described by Francis Buchanan-Hamilton in 1822, originally in the genus Ophisurus. It is a tropical, marine eel which is known from the Indo-West Pacific, including Somalia, Tanzania, South Africa, India, Pakistan, Sri Lanka, Indonesia, Polynesia, Australia, Bangladesh, Cambodia, Kenya, Madagascar, the Philippines, Malaysia, Mozambique, Seychelles, Saudi Arabia, Taiwan, China, Thailand, Vietnam, and southern Yemen. It is an anadromous species and spawns in freshwater, often in rice paddies during the rainy season, earning it its common name. It also spends time in lagoons, estuaries and coastal rivers, in which it lives in burrows in the river bottom and bank. Males can reach a maximum total length (TL) of 100 centimetres, but more commonly reach a TL of 70 cm. The rice-paddy eel is of minor commercial interest to fisheries; it is caught in bag nets and marketed fresh.
