The Green or Shore Sea Urchin, Psammechinus miliaris, is a common British sea urchin, and I found and photographed these live specimens from some tide pools on the Worms Head Causeway in Gower, South Wales. It seems a strange co-incidence that the colour of the spines is greenish terminating in pink – just like the tentacles of the Snakelocks Anemones which are found in the same habitat and location. I wonder whether there is any significance to this similarity?
