Observed senses of the environment and the organism's relationship to it in sharks:
Vision: the detection of light and distinguishing a specific range of wavelengths.
Audition: the detection of high-frequency vibrations in the medium in which the organism lives (sound).
Gustation (possibly several senses): detection of specific compounds and types of chemicals on contact (taste).
Olfaction: detection of many different chemicals dispersed in the medium in which the organism lives (smell).
Tactition/mechanoreception: detection of pressure from contact (touch).
Thermoception: detection of external heat and its absence (temperature).
Nociception: perception of physiological and/or tissue damage (pain). Intertwines with all senses.
Equilibrioception: perception of balance and orientation.
Proprioception: the perception of the position of the organism's body.
Electroreception: detection of electric fields.
The lateral line: detects movement and vibration in the surrounding water (possibly magnetic fields?)
