There is also cavernicolous (cave-dweller), from the Lat. "caverna", terricolous (living on the ground or in the soil) from the Lat. "terra" (soil or Earth), arenicolous (living in the sand), from Lat. "arena" (sand) and my personal favourite arboricolous (tree-dwelling).

-colous terms are often used in biology to describe the habitats where certain creatures can be found, or their living quarters: the most heat-resistant creature on earth is thought to be a tubicolous polychaete worm called "Pompeii worm" found in the deep-sea hydrothermal vents of the Pacific Ocean. It lives in a calcareous tube, hence the name.
