Explore the taxonomy of marine echinoderms with a dedicated focus on starfish and sea urchins !
The class Asteroidea, commonly known as starfish, includes more than 1,600 known species. These marine animals can reach over one meter in span with their arms fully extended and typically have five arms or a multiple of five, with the number potentially varying due to regeneration after an arm is lost. Their skeleton is made up of adjacent but not fused calcareous plates.
