The White Sea Urchin, Pseudoboletia maculata, is a species of sea urchin found in the Pacific Ocean. It is a common sight in various marine zones and plays a vital role in the delicate balance of these ecosystems.
Description and Characteristics
The White Sea Urchin, Pseudoboletia maculata, is a distinctive species with a white to cream-colored test (shell). Its test is typically spherical and can reach a maximum size of approximately 8 centimeters in diameter. It is covered in spines that are short and blunt, giving it a somewhat rough appearance. The spines can vary in color from white to brown, adding to its unique aesthetic. The Pseudoboletia maculata has a distinctive five-pointed symmetry characteristic of most sea urchins.
Habitat and Occurrence
The White Sea Urchin, Pseudoboletia maculata, is a common inhabitant of rocky intertidal zones and shallow subtidal areas. It is typically found in the Pacific Ocean, where its distribution ranges from Alaska to California. This species thrives in a variety of marine zones, from the intertidal, where it can withstand exposure to air during low tides, to the subtidal, where it enjoys more consistent immersion in saltwater. It often resides among kelp forests and seagrass beds, making these areas a significant part of its habitat.
Taxonomy
The White Sea Urchin, Pseudoboletia maculata, belongs to the Class: Echinoidea, Order: Camarodonta, and Family: Toxopneustidae. This classification places it among the true sea urchins, characterized by their rigid test, spines, and tube feet. The Pseudoboletia maculata is part of the diverse and well-established family Toxopneustidae, which encompasses various other species of sea urchins.
Feeding
The White Sea Urchin, Pseudoboletia maculata, is an herbivorous species. It primarily feeds on algae, including nori. Its diet plays a vital role in the overall health and balance of its marine environment. The Pseudoboletia maculata‘s grazing activities contribute to the maintenance of healthy kelp forests and seagrass beds.
