Long Spine Blue Lined Urchin (Diadema savignyi) アオスジガンガゼ
The Long Spine Blue Lined Urchin Has long spines, blue lines, and a blue ring around its perirectal cone. The spines are venomous and sharp and brittle. If you touch one the spines will break off and sting for a long time, so don’t touch. If you are wondering what is on the bottom, there is its mouth. It does have two sets of spines the very long outer ones and the shorter thin inner spines that contain the venom. Some say that the outer ones are venomous, but both should be avoided. Amami 2022
