Living in or inhabiting caves, especially referring to animals or organisms adapted to cave life.
From Latin 'caverna' (cavern) plus '-colous' (suffix meaning dwelling in or living in); literally 'cave-dwelling.'
Cavernicolous creatures like olm salamanders have lost their eyes over millions of years—but they 'see' using electroreception, proving that life adapts in the strangest ways when light disappears.
