The electroreceptors of monotremes consist of free nerve endings located in the mucous glands of the snout. Among the monotremes, the platypus (Ornithorhynchus anatinus) has the most acute electric sense. [37] [38] The platypus localises its prey using almost 40,000 electroreceptors arranged in front-to-back stripes along the bill. [34]
Ampullae of Lorenzini (sg.: ampulla) are electroreceptors, sense organs able to detect electric fields. They form a network of mucus -filled pores in the skin of cartilaginous fish ( sharks , rays , and chimaeras ) and of basal bony fishes such as reedfish , [ 1 ] sturgeon , [ 2 ] and lungfish . [ 1 ]
The elephantnose fish is a weakly electric fish which generates an electric field with its electric organ, detects small variations in the field with its electroreceptors, and processes the detected signals in the brain to locate nearby objects. [12] Weakly electric fish generate a discharge that is typically less than one volt.
Several basal bony fishes, including the paddlefish (Polyodon spathula), possess electroreceptors. The paddlefish hunts plankton using thousands of tiny passive electroreceptors located on its extended snout, or rostrum. The paddlefish is able to detect electric fields that oscillate at 0.5–20 Hz, and large groups of plankton generate this ...
The electroreceptors are located in rostrocaudal rows in the skin of the bill, while mechanoreceptors for touch are uniformly distributed across the bill. The electrosensory area of the cerebral cortex is in the tactile somatosensory area, and some cortical cells receive input from both electroreceptors and mechanoreceptors, suggesting the ...

Electroreceptors respond to electric fields. Ampullae of Lorenzini respond to electric fields, salinity, and to temperature, but function primarily as electroreceptors; Hydroreceptors respond to changes in humidity; Magnetoreceptors respond to magnetic fields; Mechanoreceptors respond to mechanical stress or mechanical strain
It’s 2011 and I’m on a plane to Miami. I’m ready to soak up some sun and kick back at my sister’s apartment in South Beach. As an afterthought, I’ve agreed to go to one of the largest electronic music festivals in the world, Ultra, for the first time.
