When I was young Boy Scouts use a piece of sea shell as a “woggle” to hold their neck scarves together at the front instead of having to tie a knot. I suppose this made it easier to get the scarf on and off. Often when at a beach I would go in search of “woggle” shells along the sea-shore.
While walking along the rocks under the cliffs at the northern end of Mangawhai Beach in March 2009 we came across this mass of “used” shells washed up by the tide. There was a large bank of them that stretched for about 20 metres. And yes. there were “wogggles” among them. Of course, the “woggle” is the hard opening in the shell remaining after it is broken and worn smooth by constant agitation of waves crashing against the shore. I still don’t know what type of shell it is!
