To inhibit fouling by marine life of an undersea structure, the part of the structure to be protect (32) is provided with a plurality of elongate fronds (20) of flexible plastics material, such that they can move against each other under the influence of water currents to create a constantly moving surface. Preferably the device is backed by a foam layer (50) which inhibits water movement against the surface of the structure thus reducing corrosion. |
