The Japanese eel (Anguilla japonica; nihon unagi (日本鰻) [2]) is a species of anguillid eel found in Japan, Korea, Taiwan, China, and Vietnam, [3] as well as the northern Philippines. Like all the eels of the genus Anguilla and the family Anguillidae , it is catadromous , meaning it spawns in the sea but lives parts of its life in freshwater.
All three eel species used as unagi have seen their population sizes greatly reduced in the past half century. For example, catches of the European eel have declined about 80% since the 1960s. The Japanese Ministry of the Environment has officially added Japanese eel to the “endangered” category of the country's Red List of animals ranging ...
The European eel (Anguilla anguilla) is listed as Critically Endangered on the global IUCN Red List of Threatened Species. While the Japanese eel (Anguilla japonica) and American eel (Anguilla rostrata) are assessed as Endangered. [16] In 2010, Greenpeace International added the American eel, European eel, and Japanese eel to its seafood red ...
After being swallowed alive, Japanese eels were able to escape from a predator fish’s stomach and swim to freedom through the fish’s gills, new research shows.
The Asian swamp eel (Monopterus albus), also known as rice eel, ricefield eel, rice paddy eel [3] or white rice-field eel, [1] is a commercially important air-breathing species of fish in the family Synbranchidae. It occurs in East and Southeast Asia, where it is commonly sold and eaten throughout the region.
Another Atlantic eel species is known: the American eel, Anguilla rostrata. First it was believed European and American eels were the same species due to their similar appearance and behavior, but they differ in chromosome count and various molecular genetic markers, and in the number of vertebrae, A. anguilla counting 110 to 119 and A ...
It is a natural parasite of the Japanese eel in its native range. The life cycle of Anguillicoloides crassus begins when the adult nematode releases thousands of eggs in the eel's swimbladder. The eggs pass through the eel's digestive tract and the larvae emerge in the water and settle onto the substrate.
Most eels live in the shallow waters of the ocean and burrow into sand, mud, or amongst rocks. Most eel species are nocturnal, and thus are rarely seen. Sometimes, they are seen living together in holes or "eel pits". Some eels also live in deeper water on the continental shelves and over the slopes deep as 4,000 m (13,000 ft).
