The second basic wound pattern, called "corkscrew" (to distinguish it from the "slash"), is the type most often seen on shark-killed seal carcasses at Sable Island. Generally it is a long clean-edged `cut' with few, if any, associated tooth punctures or rake marks. On several occasions during the late 1990s, a large number of harp seal pup carcasses washed ashore on beaches in Cape Breton and Prince Edward Island. Many of the carcasses were extensively damaged - the damage was similar to the shark-inflicted wounds seen on Sable seals.
