Water Spider (Megadolomedes australianus) (1/12)

Araneae: Pisauridae

Megadolomedes australianus  

Female Nursery Spider.

These spiders, as large as they are, can run on water where they catch insects and can even break through the surface to catch small fish larger than themselves.

They can also submerge themselves completely for protection by climbing down a plant stem in the water, where they breathe air trapped in their body hairs.
