All known Typhlopseudothelphusa species are adapted to the subterranean realm. They are depigmented (lack pigment), have no to highly reduced eyes/ eye stalks, and have elongated and slender appendages. As with all organisms adapted to the subterranean environment, these crabs occur in the deepest reaches of caves--known as the cave deep zone.[1]
