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.
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]
The electric discharge pattern of bluntnose knifefishes is similar to the low voltage electrolocative discharge of the electric eel. This is thought to be a form of bluffing Batesian mimicry of the powerfully protected electric eel. [28] Fish that prey on electrolocating fish may "eavesdrop" [29] on the discharges of their prey to detect them.
The Gymnotiformes, including the glass knifefish (Sternopygidae) and the electric eel (Gymnotidae), differ from the Mormyridae in emitting a continuous wave, approximating a sine wave, from their electric organ. As in the Mormyridae, the generated electric field enables them to discriminate accurately between capacitative and resistive objects.
Built from jelly-like materials, the self-healing batteries were developed by a team at the University of Cambridge after they took inspiration from the muscle cells of electric eels.
Electric eel anatomy: first detail shows electric organs, made of stacks of electrocytes. Second detail shows an individual cell with ion channels and pumps through the cell membrane; A nerve cell's terminal buttons are releasing neurotransmitters to trigger electrical activity. Final detail shows coiled protein chains of an ion channel.
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 electric eel is the largest of the gymnotiform fishes, growing up to more than 2 m (6.6 ft) length. Species of Gymnotus range from about 10–100 cm (0.3–3.3 ft) in total length. [ 3 ] [ 4 ]
