  Electroception
Many fish have an electroception sense, believed to be associated with the lateral line[?] system.
Sharks apparently have an electroception sense; a problem with the early submarine telegraph cables[?] was the damage by sharks that sensed the electrical pulses.
The electric eel, besides its ability to generate high voltage electric shocks, actually uses lower voltage pulses for navigation and sensing prey in the turbid waters in which it lives.

 What is Electroception?
Electroception is the biological ability either to create or to detect electric charges.
Electroception is used to increase the animal's awareness of its surrounding environment and sometimes to detect prey.
Gymnotiformes are a lineage of fish that have evolved to exploit bioelectricity and electroception.

 The senses
Additionally there are some other candidate physiological experiences which may or may not fall within the above classification, for example the sensory awareness of hunger and thirst.
The only known mammal which demonstrates electroception is the platypus (see [2] (http://instruct1.cit.cornell.edu/courses/bionb420.07/anelson/platypus.html)).
Magnetoception[?] (or "magnetoreception") is the ability to detect fluctuations in magnetic fields and is most commonly observed in birds.

"Electroception Electroception (or "electroreception")", the most significant of the non-human senses, is the ability to detect electric field electric fields.
Several species of fish, shark sharks and rays have evolved the capacity to sense changes in electric fields in their immediate vicinity.
The only mammal which is known to demonstrate electroception is the platypus platypus (see).

The male Platypus has venomous ankle spurs, used in vicious territorial battles and fights over mates.
The Platypus is one of the few mammals known to have a sense of electroception: it locates its prey in part by detecting their body electricity.
It feeds on annelid worms and insect larvae, freshwater shrimps, and yabbies (freshwater crayfish) that it digs out of the riverbed with its snout or catches while swimming.

 CC-AI-Body-HTML
The mechanisms by which electroceptive fishes construct a spatial representation from very small differences in field potentials involve comparisons of spike latencies from different parts of the fish's body (Carr et al 1986a; Carr et al 1986b).
This information is coded for many points on the body surface, and it is relayed in the same form and in somatotopic order, by the spherical cells of the electrosensory lateral line lobe, to lamina 6 of the torus semicircularis in the midbrain.
Thus, in electroception it is believed that a latency-place code is converted to a place code in which various combinations of body points are represented, although the functional organization of this place-based electroceptive map for external space is still not well understood.

 QI Talk Forum | View topic - Senses
There are other candidates, eg the senses of hunger and thirst, and direction, so that the number suggested varies between 9 and 21.
There are also senses which some animals have but we don't: "electroception" detects electric fields, "magnetoception" detects magnetic fields and is used in avian navigation systems, "echolocation", the "lateral line" used by fish to sense pressure, and infra-red vision.
It probably depends on whether you stipulate that you must be aware of the detection for it to be a sense.

 STIMULUS CODING THROUGH INTERSPIKE INTERVAL STATISTICS OF NEURAL POPULATIONS
Secondly, this is a clear example of a population-based neural code in which perceptual qualities are determined by asynchronous, temporal micropatterns of activity distributed over entire ensembles (mass statistics, correlations), rather than local activations of particular subsets of neurons (switchboards, across neuron patterns).
Stimulus coding by temporal correlation is potentially available in any sensory system that phase-locks to its adequate stimulus (auditory, mechanoception, vision, electroception).
Time and interest permitting, we will also discuss neural architectures (coincidence arrays, neural timing nets) that analyze these kinds of sensory representations.

No stranger to being hunted, and sometimes overly sensitive to his unique nature, Burnu is quick to start a fight with offending humans.
Being one of the very few species of mammals to have electroception, Burnu is an expert at locating any of the enemy in hiding by reading a body's electrical signals.
Highly effective with his native boomerang, Burnu often surprises the hidden or camouflaged enemy by being able to locate them, smack them in the head with his special alloy boomerang, and then alerting his I.W.G. comrades to their location for the kill.

It is interesting to consider the ecological pressures that might have driven the evolution of SW-sleep.
Fish inhabit an aquatic medium that allows them to rely heavily on electroception, magnetoception and olfaction to survive (66, 67).
The conquest of the terrestrial environment required a drastic change of the vertebrate sensory environment, as land dwellers in general depend heavily on visual and auditory information to survive.

Such skeptics believe the dowsing apparatus has no special powers but simply amplifies small but otherwise imperceptible movements of the hands, which has long been established to be the ideomotor effect.
However, supporters of this technique say the dowser has a subliminal sensitivity to the environment, perhaps via electroception, magnetoception, or telluric currents.
