Electric catfish or Malapteruridae is a family of catfishes (order Siluriformes). This family includes two genera , Malapterurus and Paradoxoglanis , with 21 species . [ 1 ] Several species of this family have the ability to generate electricity , delivering a shock of up to 350 volts from its electric organ . [ 2 ]
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.
The electrical discharge of M. electricus is not known to be fatal to humans. [3] M. electricus is eaten as food in certain parts of Africa. Along the shores of Lake Kainji, smoked electric catfish is a popular delicacy. [3] M. electricus is also sometimes encountered as an aquarium fish. [3]
Malapterurus electricus is a thickset fish with six mouth barbels and a single fin on its back, just anterior to the rounded tail fin. It is brownish or grayish, irregularly spotted with black, and attains a length and weight of about 1.2 metres (3 ft 11 in) and 23 kilograms (51 lb) M. electricus is capable of generating and controlling the discharge of up to 450 volts of electricity.
The electric rays are a group of rays, flattened cartilaginous fish with enlarged pectoral fins, composing the order Torpediniformes / t ɔːr ˈ p ɛ d ɪ n ɪ f ɔːr m iː z /. They are known for being capable of producing an electric discharge , ranging from 8 to 220 volts , depending on species, used to stun prey and for defense. [ 2 ]

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 also electroreceptive, meaning that they can sense electric fields. The only exception is the stargazer family (Uranoscopidae). Electric fish, although a small minority of all ...
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.
