Facts: Family: Pisauridae Scientific name: Dolomedes plantarius Common name: Fen Raft spider This fishing spider is not as common at the D. Fimbriatus. It is fast and hunts its prey down. It can run on the surface or swim under water to catch prey. If it feels threatened the spider can hide submerged for an hour.
