Electric eel skeleton, with the long vertebral column at top, the row of bony rays below. Electric eels have long, stout bodies, being somewhat cylindrical at the front but more flattened towards the tail end. E. electricus can reach 2 m (6 ft 7 in) in length, and 20 kg (44 lb) in weight. The mouth is at the front of the snout, and opens upwards.
Carl Sachs was born in Neisse (now in Poland). He was sent to Latin America by the physiologist Emil du Bois-Reymond, to study the electric eel (Electrophorus) in the same Llanos region where Humboldt had made his observations; [1] [2] [3] he took with him a galvanometer and electrodes to measure the fish's electric organ discharge, and used rubber gloves ("Kautschuck-Handschuhen") to enable ...
Electrophorus electricus is the best-known species of electric eel. It is a South American electric fish. Until the discovery of two additional species in 2019, the genus was classified as the monotypic, with this species the only one in the genus. [2] Despite the name, it is not an eel, but rather a knifefish. [3]
Featured animals: electric eel, red bellied piranha, tiger sorubim, redtail catfish. Electric eel Three mysterious deaths in three countries lead Wade to an unlikely suspect. The victims all show signs of burns on their corpses, and the Electric eel is quickly identified as the culprit. Initially reluctant to believe that the eel can inflict ...
In biology, the electric organ is an organ that an electric fish uses to create an electric field. Electric organs are derived from modified muscle or in some cases nerve tissue, called electrocytes, and have evolved at least six times among the elasmobranchs and teleosts. These fish use their electric discharges for navigation, communication ...
History of bioelectricity. The history of bioelectricity dates back to ancient Egypt, where the shocks delivered by the electric catfish were used medicinally. In the 18th century, the abilities of the torpedo ray and the electric eel were investigated by scientists including Hugh Williamson and John Walsh.
Description. It closely resembles E. electricus but differs in skull morphology, including having a depressed skull and a wide head. It has a maximum voltage of 860 volts, making it not only the strongest bioelectricity generator of the three electric eel species, but also of any animal. [3] Males get larger than females by about 35 cm (14 in).
Eel life history. Eels are any of several long, thin, bony fishes of the order Anguilliformes. They have a catadromous life cycle, that is: at different stages of development migrating between inland waterways and the deep ocean. Because fishermen never caught anything they recognized as young eels, the life cycle of the eel was long a mystery.
