Fifty-two Jamaican caves were investigated for invertebrate faunas, with the discovery of about 250 invertebrate species judged to be non-accidental residents of subterranean spaces or caves.

After Cuba, this is the richest known diversity of cave faunas on any island in the West Indies. -from Author
