Does sea urchins need to survive crashing waves low tides or other special challenges?

Yes, sea urchins are adapted to survive crashing waves and low tides. They have strong, flexible bodies that can withstand strong currents, and they often cling to rocks or other surfaces to avoid being swept away. During low tides, they can burrow into crevices or hide under rocks to stay moist and protect themselves from predators and desiccation. These adaptations allow them to thrive in challenging intertidal environments.
