The raft spider prefers to live on the banks of standing or flowing waters, in marshes and swamps, as well as in wet meadows. As the name suggests, it lurks on the water surface preying for aquatic insects, tadpoles and even small fish. When hunting it moves skillfully on the water, staying afloat thanks to its dense body hair distributing its weight, thus not breaking surface tension. In case of danger or to catch prey, the spider is able to submerge. When doing so, an air bubble forms around its body, which bursts after surfacing, releasing a dry spider from the water.
