Sea urchins manage to exist through their unique adaptations and ecological roles. They possess a hard exoskeleton and spines that provide protection from predators, while their tube feet allow them to move and feed on algae and detritus on the ocean floor. Additionally, they play an important role in their ecosystems by controlling algal growth, which helps maintain the health of coral reefs. Their ability to thrive in a variety of marine environments, from shallow coastal waters to deeper ocean floors, further contributes to their survival.

Yes, sea urchins are herbivores because they mainly feed on algae.
Sea urchins reproduce by releasing eggs and sperm into the water, where external fertilization takes place. Once fertilized, the eggs develop into larvae that eventually settle and grow into adult sea urchins. Some species of sea urchins can also reproduce by asexual means, such as splitting or budding.
Sea urchins are found generally in the sea, however they can also be found in/on rock pools or areas near to the sea.
Sea otters are secondary consumers. This because sea urchins are primary and sea otters eat sea urchins.
