What are some sea urchin adaptations?
Sea urchins have several adaptations to help them survive. To protect themselves from predators, sea urchins will react immediately if something sharp touches their shell and they will point all of their spines towards the area being poked. They are also light-sensitive. This is why they are nocturnal. This light sensitivity also allows sea urchins to move their spines in reaction to shadows. In order to protect themselves from being swept away from the powerful ocean currents and waves, sea urchins lodge themselves into holes or crevasses. Finally sea urchins, somewhat like starfish, have a certain regenerative ability. If a spine is damaged or lost, a sea urchin can rebuild it. However if there is too much extensive damage to the test, the sea urchin won't be able to heal it.
