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 ...
The American conger is a large, elongated, cylindrical fish growing to a maximum length of over 2 m (6.6 ft) and a maximum weight of over 40 kg (88 lb), though a more typical length is about a meter. The upper jaw projects further forward than the lower jaw. The dorsal fin starts just behind the pectoral fins and runs in a continuous even ...
Vallisneria americana, commonly called wild celery, water-celery, tape grass, or eelgrass, [2] is a plant in the family Hydrocharitaceae, the "tape-grasses". V. americana is a fresh water species that can tolerate salt, living in salinities varying from fresh water (0 parts per thousand) to 18 parts per thousand, although the limit to the salt tolerance is unclear, and is generally dependent ...
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.
