"The beautiful but highly poisonous flower urchin or ""Rappa Uni"" in Japanese, my favorite echinoderm. This individual has gathering rock and other debris from around its environment."

Amazed to find this is an iNat first. Skeletons and a few live individuals were common subtidally at one beach south of town. I never saw them as beach drift. This lovely animal seems to be represented on the internet primarily as a cheap novelty or gift item. It took some sleuthing just to track down the scientific name.

The bottom spike is from the NZ kina, (Evechinus chloroticus) while the top spike is from a form of kina from Rapanui, Easter Island and it is that one that I am interested in getting an ID for :) Any bright ideas @clinton :)
