Found still life with sea weed

Travelled home to Christchurch today and stopped along the Kaikoura coast for a scramble along the beach and rocks. I am always attracted to shells and bits of shells. I love the shapes and textures. This little still life contains a NZ paua (abalone), the central spiral of a Cook's Turban shell and a bit of the outer shell, a limpet shell and another shell which I can't remember the name of but it's too late to go and find my shell book.
