外見

The Strongylocentrotus purpuratus is a spherical echinoderm covered in sharp, movable spines that range from deep purple to reddish-brown. It has a hard, spiny shell called a test, making it look like a prickly underwater ball. Its spines are relatively short and uniform, unlike some long-spined urchin species.

They use tiny tube feet with suction cups to slowly crawl across the seafloor.
