Electroreception - an overview | ScienceDirect Topics
Electroreceptors of fish include ampullary receptors, which are canals opening from the surface of the fish into cavities lined with nerve cells, and tuberous receptors, found on …

Electroreception in marine fishes: chondrichthyans ...
Jun 06, 2019 · Of particular concern is how electroreceptive fishes will respond and adapt to a marine environment that is being increasingly altered by anthropogenic electric and magnetic fields. 1 INTRODUCTION Electroreception is a phylogenetically widespread sensory modality that has evolved several times throughout vertebrate evolutionary history but is most often seen in fishes, some amphibians and a few mammals.

Electroreception - Wikipedia
Electroreceptive animals use this sense to locate objects around them. This is important in ecological nicheswhere the animal cannot depend on vision: for example in caves, in murky water and at night. Many fish use electric fields to detect buried prey. Some shark embryos and pups "freeze" when they detect the characteristic electric signal of their predators. It has been proposed that sharks can use their acute electric sense to detect the earth's magnetic field by detecting the weak electric currents induced by their swimming or by the flow of o…

Electroreception | Britannica
The ability to sense other animals presumably gave electroreceptive fishes an advantage in navigating through dark or turbid water. Tuberous electroreceptors, which are found only in electroreceptive species of teleosts, are used for sensing the AC electric fields from electric organs, either for active electrolocation of objects or for social communication.

ELECTRORECEPTION « Sixth Sense Abcderium
Amazonian catfish have been captured and found to have stomachs full of weakly electric fish tails, suggesting that they use their electroreceptive sense to hunt and prey upon active electroreceptors.

Labelling of electroreceptive afferents in a gymnotoid ...
Physiologically identified primary electroreceptive afferents in the gymnotiform fish,Eigenmannia, were labelled by intracellular injection of horseradish peroxidase (HRP) in order to determine their termination sites in the posterior lateral line lobe (PLLL) (Fig. 1).

What are the functions of electroreception in fishes?
Functions of electroreception. The ability to sense other animals presumably gave electroreceptive fishes an advantage in navigating through dark or turbid water.

Which is the only animal with an electroreception sense?
There is even good evidence for a mammalian electroreceptive species: the platypus (Pettigrew 2004; Scheich et al. 1986). Electroreception is used in a number of ways by the animals that have this sense.

Which is an example of a passive electroreception?
This brief account predominantly concentrates on passive electroreception, where the weak electric fields produced by other organisms or anthropogenic sources are detected using specialized end organs.
