electroreceptor
C2Technical / Scientific
Definition
Meaning
A specialized sensory organ found in certain animals that detects electrical fields.
Any biological structure or system capable of transducing electrical stimuli from the environment into neural signals, allowing the organism to perceive electric fields, which is used for navigation, hunting, and communication.
Linguistics
Semantic Notes
This is a compound noun formed from 'electro-' (relating to electricity) and 'receptor' (a structure that receives stimuli). It refers exclusively to a biological structure, not an electronic device.
Dialectal Variation
British vs American Usage
Differences
No significant spelling or usage differences. The term is uniformly technical.
Connotations
Purely scientific, with no cultural or regional connotative variation.
Frequency
Extremely low frequency in general discourse, confined to specialist texts in biology, zoology, and neuroscience in both varieties.

Context Usage
Academic
The primary context. Used in research papers, textbooks, and lectures on animal physiology, sensory biology, and evolutionary adaptation.
Everyday
Virtually never used in everyday conversation.
Technical
Used precisely in zoological, neurological, and biomechanical descriptions, e.g., 'The shark's ampullary electroreceptors are known as the ampullae of Lorenzini.'
Examples
By Part of Speech
adjective
British English
- The electroreceptive capabilities of the platypus are remarkable.
American English
- The skate's electroreceptive system is highly studied.
Examples
By CEFR Level
- Some fish can sense electricity with special organs called electroreceptors.
- The study focused on how the morphology of tuberous electroreceptors differs between related species of weakly electric fish.
Learning
Memory Aids
Mnemonic
Think: 'ELECTRICity RECEIVER' = ELECTRORECEPTOR. Imagine a shark receiving an electric text message through its snout.
Conceptual Metaphor
A NATURAL ANTENNA FOR ELECTRICITY.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'электронный рецептор' (electronic receptor), as it is a biological organ. The correct term is 'электрорецептор'.
Common Mistakes
- Misspelling as 'electro-receptor' (hyphen is generally omitted in modern usage).
- Using it to refer to man-made electronic sensors.
- Incorrect pronunciation stress on 'elec-TRO-receptor' instead of 'elec-tro-re-CEP-tor'.

Frequently Asked Questions
Many aquatic animals (e.g., sharks, rays, platypus, some fish like catfish and elephantfish) and a few terrestrial mammals like the echidna.
No, it is a highly specialized scientific term not used in everyday language.
No, electroreception is not a sense found in primates. Humans detect electricity indirectly through other senses like touch (a shock).
Ampullary receptors detect low-frequency electric fields (e.g., from prey), while tuberous receptors are tuned to higher frequencies used in active electrolocation and communication among electric fish.
