Cover of Journal of Experimental Biology

Not every day you get a cover of your favorite animal in a prestigious journal! 

The journal cover is related to the recent paper we have published in the Journal of Experimental Biology about the vision of Diadema africanum. This sea urchin waves its sharp, venomous spines at approaching enemies and can move to avoid bright light, in spite of lacking eyes. We have shown that it uses resolving vision to approach dark objects. The spatial resolution is very coarse and is consistent with a tube-foot receptor based system, as proposed elsewhere.
