ABSTRACT:
Deep sea shark cable protectors of the invention are lengths of pipe which encircle the cable, having a plurality of spaced apart spikes extending outwardly around the circumference of the pipe to prevent the shark from gripping the cable in its mouth. The lengths of pipe are hinged and have closures for securing the pipe sections, and the pipe lengths may be made of brass or other materials. The spikes may extend from around the outer surface of the pipe or may extend from the outer perimeter of clamps which encircle the cable or which encircle and/or join pipe sections.
