Dolomedes Saccalavus
''Dolomedes'' is a genus of large spiders of the family Pisauridae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all ''Dolomedes'' species are semiaquatic, with the exception of the tree-dwelling '' D. albineus'' of the southeastern United States. Many species have a striking pale stripe down each side of the body. They hunt by waiting at the edge of a pool or stream, then when they detect the ripples from prey, they run across the surface to subdue it using their foremost legs, which are tipped with small claws; like other spiders they then inject venom with their hollow jaws to kill and digest the prey. They mainly eat insects, but some larger species are able to catch small fish. They can also climb beneath the water, when they become encased in a silvery film of air.

Raft Spider
The raft spider, scientific name ''Dolomedes fimbriatus'', is a large semi-aquatic spider of the family Pisauridae found throughout north-western and central Europe. It is one of only two species of the genus ''Dolomedes'' found in Europe, the other being the slightly larger Great raft spider, ''Dolomedes'' ''plantarius'' which is endangered in the UK. Habitat and description Raft spiders are semiaquatic, semi-aquatic and adults inhabit freshwater wetlands, specifically wet heaths and acid swamps; although juveniles are predominantly found in terrestrial vegetation surrounding wetland areas. Adults are dark brown with a conspicuous white, cream or yellow stripe along both sides of their abdomen and thorax. Juveniles are similar in appearance but often have green translucent legs. As is common in other spiders, female raft spiders (body length: 9–22mm) are usually larger than males (body length (9-15mm). Dolomedes fimbriatus was described in chapter 5 of the book ''Svenska Sp ...
