𝘛𝘳𝘪𝘱𝘯𝘦𝘶𝘴𝘵𝘦𝘴 𝘷𝘦𝘯𝘵𝘪𝘤𝘰𝘴𝘶𝘴, also known as the white sea urchin or West Indian sea egg, is native to the Atlantic Ocean and lives on reefs and seagrass beds.  It has short and dense spines and is white or cream-colored. They typically have a lifespan of 2 to 3 years and grow to a body size of 11 cm. The white sea urchin plays an important role in the marine ecosystem by controlling algal populations to help maintain reef diversity. White sea urchins have a very curious behavior, they like to cover themselves with objects found in their habitat, such as pieces of algae or seashells. They do this to protect themselves from excess light and as camouflage for protection against predators.
