Polarized light direction/detection
This is used by bees to orient themselves, especially on cloudy days. Humans can learn to roughly detect large areas of polarization by an effect called Haidinger\’s brush.
Other internal senses
An internal sense is "any sense that is stimulated from within the body". This involves numerous sensory receptors in many of our internal organs, such as stretch receptors that are neurologically linked to the brain.
They can sense or control the respiratory rate, vomiting, blushing of skin, bloating, acid reflux, gag reflex, sensation of fullness, etc.
The lips, hands, feet and sex organs have more sensory neurons than other parts of the body, so the homunculus – the relative representation of each body part in the brain – has correspondingly large lips, hands, feet, and genitals.
