Water surface organisms (Neuston)

　Sea water strider, flow algae, and other organisms that live while floating on the surface of the water are called neuston. They are collected with a net called a neuston net, which is used to tow them across the surface of the water.

The net is towed on the sea surface to filter seawater and collect neuston. Since floats are attached to both sides of the frame, the net can be towed while always catching the surface of the water without the net mouth being submerged in the water.
