[4] Adults are dark brown with a conspicuous white, cream or yellow stripe along both sides of their abdomen and thorax.

[5] Dolomedes fimbriatus was described in chapter 5 of the book Svenska Spindlar by the Swedish arachnologist and entomologist Carl Alexander Clerck.

Like many other species of the genus Dolomedes (Greek translation= crafty or wily),[6] the raft spider typically hunts on the surface of the water with its front appendages outstretched and relies on aquatic vibrations to detect prey.

[4] To avoid predation by birds, the raft spider can fully submerge itself in water and has been known to hide underwater for several minutes.

[11] This behaviour is regarded as unusual among biologists as it can prevent both the male and the female from copulating successfully.
