Well, the article certainly did not say that it was a species of sea urchin. It said it was "An exploding super nova suspended in liquid and time, with bright reddish-brown spines radiating out from a never blinking eye" - and the diadema link, which goes to a page that says the word has several meanings, wasn't sufficiently helpful. Thus I couldn't find any context to explain what the article was talking about - one of our criteria for deleting articles on sight.
I have restored the page and added in the bit that it is a sea urchin, without the exaggerated description. Please note that the accompanying image will stay deleted - the first deleted version said it was used "with permission" from the photographer, making it unusable for use in Wikipedia. In light of that, the claim in the second version - that the image is licensed under GFDL - seems dubious. It might help if you indicate which website you got it from.
