Trichobothrial mediation of an aquatic escape response:

Directional jumps by the fishing spider, Dolomedes triton,

foil frog attacks

Dolomedes triton at rest on the water surface. Dimples surrounding each leg tip and the anterior part of the body show where the spider's weight is being supported by deformations in the water surface.
