The Five Senses?

Many people seem to think there can be no more but the five traditional senses of sight, hearing, smell, taste, and touch. In a way they are right if you assume that only the ones most obvious to humans are to be included. But surely there are senses in Earth and beyond that you and I have dreamed of. But a lot of these senses which I have scouted out through sources depends on what you define as a sense. Like whether you decide to lump the sense of warmth and coolness in the sense of feeling, or whether you want to include the senses (or are they instincts?) that animals, plants, and (conceivably) rocks have but most humans evidently don’t. I thought I should share this to anyone interested in senses.

The radiation senses

  1. Sight, which would include seeing polarized light and seeing without eyes, such as the heliotropism or sun senses of plants.
  2. The sense of awareness of one’s own visibility or invisibility and the consequent competence of advertise or to camouflage via pigmentation control, luminescence, transparency, screening, behavior, etc.
  3. Sensitivity to radiation other than visible light, including radio waves, x-rays, gamma rays etc., but omitting most of the temperature and electromagnetic senses.
    4.Temperature sense, including ability to insulate, hibernate, estivate, etc. This sense is known to have its own separate nerve networks.
    5.Electromagnetic senses, which includes the ability to generate current (as in the electric eel), awareness of magnetic polarity (possessed by many insects) and a general sensitivity to electromagnetic fields.

The feeling senses
6. Hearing, including sonar, and the detection of infra- and ultra-sonic frequencies beyond ears.
7. Awareness of pressure, particularly underground and underwater, as through the lateral line organ of fish, the earth tremor senses of burrowers, the barometric senses, etc.
8. Feel, particularly touch on the skin and the proprioceptive awareness of intra- and intermuscular motion, tickling, vibration sense (such as the spider feels), cognition of heartbeat, blood circulation, breathing, etc.
9. The sense of weight and balance.
10. Space or proximity sense.
11. Coriolis sense, or awareness of effects of the rotation of the earth.

The chemical senses
12. Smell, with and beyond the nose.
13. Taste, with and beyond the tongue or mouth.
14. Appetite, hunger and the urge to hunt, kill or otherwise obtain food.
15. Humidity sense, including thirst, evaporation controls and the acumen to find water or evade a flood.

The mental senses
16. Pain: external, internal, mental or spiritual distress, or any combination of these, including the impulse and capacity to weep.
17. The sense of fear, the dread of injury or death, of attack by vicious enemies, of suffocation, falling, bleeding, disease and other dangers.
18. The procreative urge, which includes sex awareness, courting (perhaps involving love), mating, nesting, brooding, parturition, maternity, paternity, and raising the young.
19. The sense of play, sport, humor, pleasure and laughing.
20. Time sense and, most specifically, the so-called biological clock.
21. Navigation sense, including the detailed awareness of land- and seascapes of the position of the sun, moon, and stars, of time, of electromagnetic fields, proximity to objects, probably Coriolis and other sensitivities still undefined.
22. Domination and territorial sense, including the capacity to repel, intimidate or exploit other creatures by fighting, predation, parasitism, domestication or slavery.
23. Colonizing sense, including the receptive awareness of one’s fellow creatures, of parasites, slaves, hosts, symbionts, and congregating with them, sometimes to the degree of being absorbed into a superorganism.
24. Horticultural sense and the ability to cultivate crops, as is done by ants who grow fungus, or by fungus that farms algae.
25. Language and articulation sense, used to express feeling and convey information in every medium the bee’s dance to human literature.
26. Reasoning, including memory and the capacity for logic and science.
27. Intuition or subconscious deduction.
28. Esthetic sense, including creativity and appreciation of music, literature, drama, or graphic and other arts.
29. Psychic capacity, such as foreknowledge, clairvoyance, clairaudience, psychokinesis, astral projection and possibly certain animal instincts and plant sensitivities.
30. Hypnotic power; the capacity to hypnotize other creatures.
31. (My Favorite) Relaxation and sleep, including dreaming, meditation, brainwave awareness and other less-than-conscious states of mind like pupation, which involves cocoon building, metamorphoses and, from some viewpoints, dying.

The spiritual sense
32. Spiritual sense, including conscience, capacity for sublime love, ecstasy, sense of sin, profound sorrow, sacrifice and in rare cases, cosmic consciousness.

How about equilibrioception, the sense of balance?

Not all of those listed are senses, as such, but speaking as someone without one of the “traditional five” I can confirm that humans certainly have more. Balance is the obvious one, as is spacial awareness, which, combined with sound, allow us to use echo-location to map our environment.
