The females of these Fishing Spiders are probably the largest representatives of this genus, while the males only reach almost a centimeter in length. The genus owes its common name to the fact that small fish can also be captured. It is a very fast and agile species that requires some preparation and planning to master. Otherwise the animal will escape faster than you can see. Optically it resembles Dolomedes tenebrosus, an actual difference can only be found under the microscope.
