Where seen? This spicy-looking red sea urchin was seen once along an East Coast Park shore that has since been affected by coastal works.

The one we saw had a body diameter 5-8cm, yellowish. Spines
(1.5-2cm) longer than the more common White sea urchin, and banded white and red. Spines on the upper side are sharp. Spines on the underside have spade-like tips. It has long tube feet.

East Coast Park, May 09
