The geology around Hwasun Beach is remarkable but here are some photos of beach life – washed-up seaweed and a rock covered with shellfish. It makes me realise how little I know about seaweed, both in terms of the biology and the uses to which they’re put.
And finally the shellfish, encrusted on a rock. I assume this is a slow-motion competitive environment, with each creature vying for space with those around it.
