The Electric Sense of Weakly Electric Fish

Annual Review of Physiology, 1984
Recent studies of electroreception have been particularly successful in three different areas: Electroreceptors are tuned to the dominant frequency of the animal's EOD, and their tuning follows natural and experimentally induced shifts in EOD frequency.

An Electrical Receptor in Fishes

Nature, 1958
CERTAIN families of fishes, namely the Mormyridae of tropical Africa and the Gymnotidae of Central and South America, possess a small electric organ which exhibits intermittent activity. Lissmann1 found that Gymnarchus niloticus Cuv., swimming freely, emitted pulses at an even rhythm of about 300 per sec.; the frequency was unaffected by the activity ...

Electricity and fishing - a dangerous mix

Burns, 2011
The advent of fishing rods made of carbon fiber and graphite rods has greatly increased the risks of electrical injuries associated with fishing. The braided fishing lines and metal hooks put the fishermen at risk for electrical injuries.We review our burn center's experience with electrical injuries related to fishing activities during the last four ...

Electric Receptors in a Non-electric Fish (Clarias)

Nature, 1963
IT is now well established that certain fish can detect objects electrically. These fish have weak electric organs, and set up an electric field in the surrounding water. A nearby object distorts this field, and the distortions are detected by the fish. The electric receptors are sense organs communicating with the water by means of jellyfilled canals.

Electrical sensitivity of a weakly electric fish

Life Sciences, 1967
Abstract The South American gymnotid, Sternarchus albifrons produces a weak electric field of high frequency (600–1000 Hz) by means of a caudal electric organ (1,2). Electroreceptor organs have been found in the skin, innervated by the lateral line nerve (2,3). Electrical sensing by several other gymnotids has been studied (2,4–6).

Sex Differences in Electric Signaling in an Electric Fish

Science, 1972
The electric discharge of Sternopygus macrurus is distinctly different from the discharges of ten sympatric species of electric fish in Guyana, South America. Sternopygus is the first known example of a fish with sexually different electric discharges.

The electric field of a weakly electric fish

1994
Freshwater fish of the genus Apteronotus (family Gymnotidae) generate a weak, high frequency electric field (< 100 mV/cm, 0.5-10 kHz) which permeates their local environment. These nocturnal fish are acutely sensitive to perturbations in their electric field caused by other electric fish, and nearby objects whose impedance is different from the ...
