Dolomedes minor, also known as the nursery web spider (not to be confused with members of the family Pisauridae), is a large fishing spider endemic to New Zealand. Female spiders can have a legspan of over 60 mm.
The spider is a pale brown colour, with lighter brown or grey stripes running along the lateral edges of the body. Other stripes and markings help it blend in with its environment, including a stripe running through the middle of its body to the middle of its abdomen - which is less prominent in its relative D. aquaticus.
