The Pencil Urchin (Eucidaris tribuloides), also known as the mine or club urchin, is a fascinating creature with its distinctive brown body and thick, stubby spines. These spines not only serve as protection but also allow the urchin to grip onto surfaces, especially as it ages and its spines become coated with algae, enhancing its camouflage.
Active and mobile, Pencil Urchins are adept at searching for food, primarily grazing on encrusting and other types of algae. Their behavior makes them valuable members of a marine ecosystem, helping to control algal growth. They thrive in rocky and sandy substrates, where they can burrow into crevices for safety and feeding.
Creating an aquarium environment that mimics their natural habitat—complete with rocks and hiding spots—will ensure their health and happiness. These urchins not only add ecological balance but also contribute an interesting visual dynamic to marine tanks!
Pencil Urchins come in a variety of sizes from 1 to 3.5 inches.
