The Hairy Pincushion Urchin is also known as the Sea Egg, and the Priest-hat Urchin. It has five or ten double rows of white and red spines separated by spaces of red, purple, white or black. To camouflage itself, it often covers itself with rocks, sponges, shells, or algae. In addition to camouflage, this provides shade, and in some cases, a food source. These urchins work wonders in aquariums that suffer from filamentous algae infestation, consuming this undesirable algae quickly.
It is extremely difficult to breed in an aquarium with no distinguishing characteristics to help differentiate it from its mate.
If there is insufficient algae for it to graze on, the Hairy Pincushion Urchin should be fed dried seaweed.
