"More than 5 senses"

Hmm... well, the very word 'senses' gets a bit ambiguous when we move beyond the standard 5. Proprioception might be considered to be a combination of a couple of others by some.

We have to be careful not to arbitrarily move some 'abilities' into the category of basic senses.

Obviously, there is much disagreement as to whether some claimed senses are real... as in telepathy, precognition...etc.

No matter how we define our own list, attributing any of our own senses to non-human entities is problematic. (DO plants fee pain?)

As a long-time reader of science fiction, I have enjoyed imagining & speculating about concepts that I have NO notion of how to test for or evaluate. Frank Herbert gave us interesting ideas in "Whipping Star" and other stories, but my interaction with the Sun is limited to night & day and sunscreen lotion.
