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.
