Common name: Spotted Sea Urchin
General information
The Spotted Sea Urchin, Pseudoboletia maculata, is a distinctive echinoderm known for its striking appearance and the role it plays in marine ecosystems. This species is characterized by its round body covered with long, slender spines that are typically banded with contrasting colors, often giving it a spotted look. These spines are not only for protection but also aid in locomotion and trapping detritus for camouflage.

Care
In the aquarium, Pseudoboletia maculata requires a stable environment with ample live rock and a sandy substrate to mimic its natural habitat. It is important to maintain high water quality with stable parameters, as sea urchins can be sensitive to fluctuations. They are generally peaceful and can coexist with a variety of tank mates, but care should be taken to ensure they do not become prey to aggressive fish.
Reproduction
Spotted Sea Urchins reproduce by releasing gametes into the water column, a process known as broadcast spawning. In the aquarium, this behavior is less common but can occur in well-established systems. The resulting larvae are planktonic and go through several developmental stages before settling to the bottom and metamorphosing into juvenile urchins.
Habitat
Pseudoboletia maculata is found in tropical and subtropical waters, often inhabiting coral reefs, seagrass beds, and rocky substrates. They play a crucial role in their ecosystems by grazing on algae, which helps prevent overgrowth and maintain the balance of reef communities.
