The British Museum in London, England has collections of old spearheads and arrowheads that were made with the stingers from stingrays on New Zealand and some Polynesian islands in the Pacific Ocean. Stingray spears could only be used one time because the stingers would stick in the body due to all the tiny barbs on the stingers. The stingers would detach from the spear and stick in a body.
