Viewer Tip: Look out for broadcast spawners on the beach in early spring; you may see some cloudy waters in tide pools from sea anemones, sea stars, or urchins. The Port Townsend Marine Science Center reminds you to use gentle, wet hands if you touch anything and leave tide pool animals where you find them. These simple steps will reduce any stress or impact to the animals.
