Although Schmidt did not directly observe eel spawning, or even find ready-to-spawn adult eels, he deduced the following about the life history of the eel, based on the size distribution of the leptocephali he collected: The larvae of European eels travel with the Gulf Stream across the Atlantic Ocean from the Sargasso Sea, and grow to 75–90 ...
The American eel (Anguilla rostrata) is a facultative catadromous fish found on the eastern coast of North America. Freshwater eels are fish belonging to the elopomorph superorder, a group of phylogenetically ancient teleosts. [2] The American eel has a slender, supple, snake-like body that is covered with a mucus layer, which makes the eel ...
European eels are normally around 45–65 centimetres (18–26 in) and rarely reach more than 1.0 metre (3 ft 3 in), but can reach a length of up to 1.33 metres (4 ft 4 in) in exceptional cases. [8] In addition, they range from having 110 to 120 vertebrae. [9] While European eels tend to live approximately 15–20 years in the wild, some ...
The European conger is the heaviest of all eels. Eels are elongated fish, ranging in length from 5 cm (2 in) in the one-jawed eel (Monognathus ahlstromi) to 4 m (13 ft) in the slender giant moray. [7] Adults range in weight from 30 g (1 oz) to well over 25 kg (55 lb). They possess no pelvic fins, and many species also lack pectoral fins.
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.
However, these eels do not necessarily reproduce every year-they will sometimes wait until conditions are right in order to migrate and breed. The European eel can spawn starting at 7 years old, and the oldest of this species that has been found in the wild was 85 years of age. [22]
European congers have an average adult length of 1.5 m (5 ft), a maximum known length of around 2.133 m (7 ft) (possibly up to 3 metres (9 ft 10 in) for the largest specimens), [2] and maximum weight of roughly 72 kg (159 lb), [3] making them the largest eels in the world by weight. They can be rivaled or marginally exceeded in length by the ...
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. It has been introduced to two areas ...
