Phreatoicidae is a family of blind, freshwater isopods. They have survived apparently unchanged for 350 million years, and are only found in South Africa, India, Australia and New Zealand. They were first found near Christchurch in 1882 by Charles Chilton.[2] The family Phreatoicidae now contains 13 genera:[3]
