A special display is dedicated to sea urchins and other living and fossil echinoderms. This exhibition exemplifies biology, ecology, and phylogeny of these marine organisms. The specimens arranged according to the echinoid systematics assemble the most important sea urchin groups and also extant crinoids from the Caribbean.
