There are four main symbiotic relationships that sea urchins have : mutualism, commensalism, parasitism, and competition. To explore these relationships, let's consider a natural ecosystem such as the ocean.
Echinoderms classified as sea urchins are spiky, spherical echinoderms. Every ocean's seabed is home to about 950 different species of sea urchins, which can be found from the intertidal shoreline to 5,000 metres below the surface. Sea urchins have spherical, hard shells (tests) that range in length from 3 to 10 cm and are covered in spines, while the black sea urchin can have spines that are up to 30 cm long. Sea urchins crawl slowly on their tube feet.
