Black Short Spine Urchin

The Black short spine Urchin (Echinometra lucunter) also known as the rock-boring urchin because they bore holes in the substrate. These urchins are easily recognizable by their short, thick black spines, which are typically found in coral reefs and rocky seabeds. These urchins are primarily herbivores, grazing on algae and detritus, and play a crucial role in maintaining the health of both natural reef ecosystems and reef aquariums. By feeding on various types of algae and breaking down detritus, they help keep the environment clean and prevent algae from overgrowing.

In aquariums, Black Urchins often add a touch of character, moving gracefully around the tank with the help of their many tube feet. They may even carry small shells or objects, which they collect as they roam. Peaceful and non-aggressive, Black Urchins coexist well with other aquarium inhabitants. They thrive in environments with plenty of rocks and crevices, which provide shelter and foraging opportunities. This makes them a great addition to a variety of aquarium setups, where they contribute both to the tank's aesthetic and its ecological balance.
