noun
- a sensory receptor that detects electrical fields or currents in the environment
Usage: biology; specialized term used in neuroscience and zoology
Examples
- Sharks use electroreceptors called ampullae of Lorenzini to detect the electrical signals produced by muscle contractions in prey.
- Electric eels have specialized electroreceptors that allow them to navigate and communicate in murky water.
- The electroreceptors in some fish species are sensitive enough to detect voltage changes of less than one microvolt.
- Electroreceptors evolved in aquatic animals as an adaptation for hunting and navigation in low-visibility environments.
- Scientists study electroreceptors to understand how animals perceive their surroundings through electrical sensing.
