Description
[edit]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]
Etymology
[edit]The suffix Typhlo- from the genus name Typhlopseudothelphusa is derived from Greek typhlos for "blind", because complete blindness of the crabs from this genus due to the troglobitic lifestyle.
Distribution
[edit]Typhlopseudothelphusa crabs are known from fresh water in karstic caves from Central America.
