Exploring rockpools on Iron Island, Kimberleys.

Poking around rockpools is fun.  And the rockpools of remote Iron Island are no exception to this rule. Whilst we were awaiting the return of the landing craft, I found and photographed this bunch of unusual and quite attractive striped shells.  Not being an expert conchologist, I'm guessing that they look like small versions of trochus sea snails.
Trochus snails are sought after to make mother of pearl products such as buttons, beads or pendants.
I've heard that the meat of the mollusc is edible too.  It might be OK for a snack or two, if I was ever cast away on Iron Island.
If any experienced shell collectors are reading this blog, please feel free to enlighten me, or correct me on my trochus pics. Thanks.
