Ecological Aspects of Electroreception
1978Proper placement of electroreception as an ecosensory function within the array of the different sensory modalities seems difficult; however, some close relationship with vision can be established. Among the vertebrates, visual receptors and the many accessory dioptric and related structures are most highly developed in birds and fishes, but for ...

Morphology of Electroreceptive Sensory Organs
2006The morphology of electroreceptive organs in lampreys and their larvae, different fishes, aquatic amphibians, and monotreme mammals is described. The sense organs vary from superficial end buds in lampreys, to ampullary organs and tuberous organs in many fishes and amphibians, to specialized mucous glands in the monotremes.

Electroreception and communication in fishes
1996This concise review focuses on recent advances in the function and mechanism of electroreceptive systems in lower aquatic vertebrates and elucidates the sophisticated principles of communication, prey detection and orientation in these organisms. An introduction into electroreceptors, electric organs and sensory functions is followed by a review of ...

Electroreceptive properties ofSilurus glanis (L.)
Experientia, 1974Silurus glanis (L.) hat elektrische Sinnesorgane, deren Eigenschaften mit denen desIctalurus nebulosus ubereinstimmen: die Rezeptoren sind tonisch, die obere Frequenzgrenze liegt bei etwa 25 Hz, und der Schwellenwert betragt ungefahr 10−10 A/mm2. Sie konnten also, wie beiIctalurus, sowohl dem Beutefang als der Orientierung dienen.

Taxonomy of Electroreceptive Teleosts
1990Taxonomy is viewed by some as a dull and boring subject. This is understandable when one thinks of some old-fashioned museums that present endless shelves of, say, dead fish preserved in alcohol. Very often these fish are unattractively bleached, unnaturally oriented, difficult to see through the jar, and covered partly by an identifying tag.

Electroreception in Elasmobranchs: Sawfish as a Case Study
Brain, Behavior and Evolution, 2012The ampullae of Lorenzini are the electroreceptors of elasmobranchs. Ampullary pores located in the elasmobranch skin are each connected to a gel-filled canal that ends in an ampullary bulb, in which the sensory epithelium is located. Each ampulla functions as an independent receptor that measures the potential difference between the ampullary pore ...

Electroreception and the compass sense of sharks
Journal of Theoretical Biology, 1995Abstract Elasmobranchs have an electric sense that is sensitive enough to detect electric fields as weak as those induced through their bodies as they swim through the earth’s magnetic field. Because the intensity and direction of these fields are related to the speed and direction of the movements that cause them, elasmobranchs could use their ...

Active Electroreception in Weakly Electric Fish
2017American gymnotiformes and African mormyriformes have evolved an active sensory system using a self-generated electric field as a carrier of signals. Objects polarized by the discharge of a specialized electric organ project their images on the skin where electroreceptors tuned to the time course of the self-generated field transduce local signals ...
