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.
Electroreception and electrogenesis are the closely related biological abilities to perceive electrical stimuli and to generate electric fields. Both are used to locate prey; stronger electric discharges are used in a few groups of fishes (most famously the electric eel, which is not actually an eel but a knifefish) to stun prey.
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).
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]
Similar to the electrocytes in eels’ muscles, the hydrogel material can deliver a current while also being soft and malleable enough to withstand different conditions without losing conductivity.
5 April 2009. (2009-04-05) –. 28 May 2017. (2017-05-28) River Monsters is a British and American wildlife documentary television series produced for Animal Planet by Icon Films of Bristol, United Kingdom. It is hosted by angler and biologist Jeremy Wade, who travels around the globe in search of big and dangerous fish.
Among the electric fishes are electric eels, knifefish capable of generating an electric field, both at low voltage for electrolocation and at high voltage to stun their prey. An electric fish is any fish that can generate electric fields, whether to sense things around them, for defence, or to stun prey. Most fish able to produce shocks are ...
