Sea Urchins Physiology
Sea urchins' physiology refers to the biological processes and functions specific to these echinoderms. This includes their unique reproductive system, which involves the release of gametes into the water for external fertilization. Sea urchins also possess a water vascular system that aids in locomotion and feeding, as well as a complex network of tube feet for movement and sensory perception. Additionally, their spiny exoskeleton provides protection and structural support, while their specialized digestive system allows them to feed on algae and other marine organisms. Overall, sea urchins' physiology is adapted to their oceanic environment and plays a crucial role in their survival and reproduction.
