The term "endolith", which defines an organism that colonizes the interior of any kind of rock, has been further classified into five subclasses:<ref>{{Cite journal |url=http://jsedres.sepmonline.org/cgi/content/abstract/51/2/475 |archive-url=https://web.archive.org/web/20101230015229/http://jsedres.sepmonline.org/cgi/content/abstract/51/2/475 |url-status=dead |archive-date=2010-12-30 |first1=Stjepko |last1=Golubic |first2=E.

;Chasmoendolith: Colonizes fissures and cracks in the rock connected to the surface (''chasm'' = cleft)
;Cryptoendolith: Colonizes structural cavities within natural pore spaces within the rocks. These pores are usually indirectly connected to the rock surface; (''crypto'' = hidden) 
;Euendolith: Penetrates actively into the interior of rocks forming channels and grooves that conform with the shape of its body, rock boring organism (''eu'' = true)
;Hypoendolith: Colonizes the pore spaces located on the underside of the rock and that make contact with the soil (''hypo'' = under)
;Autoendolith: Capable of rocks formation by mineral depositation (''auto'' = self)
