Only along the west coast of North America can you see this beautiful (but prickly) animal. Found in tide pools and shallow coastal waters, they are part of a fascinating web of life — sea otters eat urchins, urchins eat kelp, and kelp provides habitat for many different forms of marine life. The tight relationship between these species offers a perfect example of why we can't manage things in isolation. Removing one piece of the equation can create huge shifts in the overall ecosystem.

Have you explored a tide pool lately? What's your favourite tide pool find?
