So i went for a walk down by point walter and theres is a nice point that sticks out in the water with loads of rocks just under the water, thought I would have a look, sure enough first rock i picked up had these snails all over it, and what looked like some amphipods. my questions is does anyone know what type of snail these guys are and are they of any use to us and are you allowed to take rock from the beach here in WA, and if you did how would you clean it
