Clear water allows more sunlight to penetrate the seabed, providing urchins with the energy they need to grow and reproduce. In addition, clear water provides urchins with better visibility of predators, allowing them to better avoid becoming prey. Sea urchins are used as indicators for public aquariums. If the water is too warm (warmer than 20 degrees), the kelp does not thrive as well. Sea urchin larvae have been shown to react with particular sensitivity to CO2-induced reductions in seawater pH (14). To preserve body heat sea otters tend to spread out or fold up their feet.
