Don't Cone snails stab their harpoons in and break them off when they sting?

Cone snails are not uncommon in the waters off Northern Queensland in Australia, with about a third of all species found there. They can release a number of different types of toxins, and there have been the occasional bites - see http://www.abc.net.au/news/2015-06-09/c … nd/6533710

As far as I am aware the harpoon is like a disposable, hypodermic needle, and once it is used to inject venom it is discarded. The cone shell can lock and re-load another harpoon to strike again.
