Mespilia globulus is an invertebrate from the genus Mespilia which is part of the Temnopleuridae family. The Blue Tuxedo Urchin, also known as the Sphere Urchin or Globe Urchin, has five to ten broad-colored bands usually blue or black, with red, brown, or dark spines. This very striking combination, gives it the “formal” look and thus the name “Tuxedo Urchin.” During the day, it will hide among the rocks, in crevices, or under plants in a sandy substrate. At night, it will emerge to graze on the algae near its home. The opening at the top of the sea urchin is where waste is removed and sperm and eggs are released.
