My name is Roberto Márquez, I have forty and some more years of age and currently I live in Seville, SPAIN.

My great passion is the sea, navigation and the world travels. I have been, since I was a kid, collector of seashells. Sea urchins always interested me, but not does a long time, when I really started to classify and put my collection in order.

This space is intended to be a open window to sea urchins collectors who wish to make exchanges with me, updates are regular and the species photographed are availables at the moment.

I request specimens perfectly classified, with or without spines, with the greatest number of available data and in good repair, not broken or damaged examples, please.
