Strongylocentrotus purpuratus
The purple sea urchin is a spiky little creature that lives in the ocean. It has a hard shell covered in sharp spines, which helps protect it from hungry animals.
Hábitat: Coastal areas
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.
