Only 2.5cm (1 inch) long, they can survive water twice as salty as the sea, freshwater, hot water at 38 deg. C and, when the water dries up seasonally, they can live up to 2 months out of the water breathing air through their skin. When out of the water, they seek out crab burrows and, lying on their side, jump on insect prey.
