Te Kawaruwaru. Shark rattle. This fishing implement is made for the specific purpose of attracting sharks in the water. The kawaruwaru is submerged in the water by the fisherman and rattled to emit sounds to attract the sharks. This kawaruwaru consists of three large cassus reefa shells, each perforated at one edge. A rusty metal wire is threaded through each shell and looped to gather all three together onto a central metal loop. The metal wire is connected to a loop of thickly plaited te kora (coconut sennit) incorporated with commercial fibre. A reel of extra fibre is also attached. The shells have extra perforations in the surface which enables water to flow also help to create sound underwater. Two of the cassus shells are orange-yellow in colour, and one is grey on the exterior.
