claimStargazers are unique among strongly electric fish because they do not use electrolocation.
claimSharks and rays (Elasmobranchii) rely on electrolocation using their ampullae of Lorenzini during the final stages of their attacks.
claimThe electric eel locates prey by generating a weak electric field and then discharging its electric organs strongly to stun the prey, whereas the electric ray uses passive electrolocation.
claimThe electric eel, a member of the Gymnotiformes, uses low-voltage electrolocation and generates high-voltage electric shocks to stun its prey.
claimElectrolocation is categorized into passive electrolocation, which senses existing electric fields, and active electrolocation, which involves the animal generating its own electric field.

referenceHeiligenberg W (1974) studied electrolocation and jamming avoidance in the electric fish Hypopygus (Rhamphichthyidae, Gymnotoidei), which uses pulse-type discharges.
claimRibbon-fin propulsion may provide enhanced maneuverability with reduced turbulence for electric fish when they are electrolocating and approaching prey organisms.
claimMormyroid and gymnotiform fishes exhibit phenotypic convergence in body form, swimming behavior, reproductive behavior, ecology, nocturnal activity patterns, electric signals, and the neuronal algorithms used to avoid jamming of active electrolocation and communication.
referenceWalter Heiligenberg published 'Principles of electrolocation and jamming avoidance in electric fish: a neuroethological approach' in 1977, which discusses the neuroethology of electric fish.
Electroreception - Simple English Wikipedia, the free encyclopedia simple.wikipedia.org 1 fact
claimElectroreceptive animals use electrolocation to determine the location of objects, which is particularly useful in ecological niches where vision is limited, such as in caves, murky water, or at night.
Electroreception, electrogenesis and electric signal evolution pubmed.ncbi.nlm.nih.gov 1 fact
claimActive electroreception, or electrolocation, occurs only in the teleost lineages Mormyroidea and Gymnotiformes, where the animal generates a weak electric-organ discharge (EOD) of less than 1 volt and detects distortions in the resulting field using high-frequency-tuned tuberous electroreceptors.

measurementSome groups of elasmobranchs and teleosts generate weak electric-organ discharges (EODs) of less than 10 volts or strong EODs of greater than 50 volts to facilitate communication or predation, though these groups do not perform electrolocation.
