Dolomedes aquaticus is a fishing spider that lives and hunts along the gravel banks of unforested New Zealand rivers. It prefers open riverbanks where it lives under rocks, usually less than 5 metres from the river. Its colouring allows it to blend in with river stones. Normally nocturnal, it sits and waits for its prey after dark, and can survive for short periods under the water.
