  15. Praeger on turloughs • ‘The animals of the turloughs have not been examined but the abrupt changes of water-level would not seem to be favourable to the presence of any varied or characteristic fauna.’ Praeger on The Burren • ‘The fauna (not yet fully examined) offers little of remark.’

  16. Fairy Shrimp Tanymastix stagnalis • Primitive freshwater crustacean • Lives in temporary cool water pools with no fish • 7 Irish sites; most in the east Burren wetlands • Eggs survive drying, hatch after rewetting
