![]() While these small basins at the ocean’s edge typically range from mere inches to a few feet deep and a few feet across, they are packed with sturdy sea life such as snails, barnacles, mussels, anemones, urchins, sea stars, crustaceans, seaweed, and small fish.Īs ocean water retreats outside the tide pool during low tide, the resident marine life must endure hours exposed to the sun, low oxygen, increasing water temperature, and predators such as wading birds that specialize in dining in these shallow pools. It is illegal to do so in many areas.įormed in depressions along the shoreline of rocky coasts, tide pools are filled with seawater that gets trapped as the tide recedes. If you peek under a rock, put it back where and as you found it.Find footholds on bare rocks, which are less slippery than those colonized with algae and other sensitive sea life.Bring a bag with you to pick up any plastic, paper, glass, or metal trash on the beach.The best time to visit tide pools is at low tide.Then, before heading home, take the time to share discoveries and stories over a cup of chowder at Bob’s Chowder Bar, a steaming bowl of mussels at Adrift, or some sweet Dungeness crab at Anthony’s. Now, armed with this knowledge and your own curiosity, gather your family, your picnic, a guide book, and maybe a magnifying glass, and go search for some of the most interesting treasures in Anacortes! Don’t collect, disturb, or destroy tide pool organism it’s not only poor etiquette, it’s against the law.Return any disturbed or lifted rocks to their original position.Do not pick up or remove anything from a tide pool.(This once stellar ecosystem is only now recovering from being destroyed in 1995, when the footsteps, curiosity, and thoughtless actions of some 1,200 students and individuals trampled the tide pool on a day with an exceptionally low tide.) Elsewhere, walk only on large, bare rocks-many creatures use rocks for cover and can be crushed. At Rosario Beach, stay on the designated trail marked by secured ropes.Being a good tide-pooler means following good beach etiquette: So, while intertidal creatures have adapted to many conditions, they haven’t adapted to human impacts. subtidal zone, always under water (all lower intertidal species, plus fish, squid, whales, etc).lower intertidal zone, out of water only during low tides (all mid intertidal group creatures, plus eelgrass, sea cucumbers, sea stars, sea urchin). ![]() mid intertidal zone, covered and uncovered twice a day, as the tide comes in and goes out (anemones, barnacles, hermit crabs, mussels, whelks).upper intertidal zone, covered with water only during high tide (barnacles, periwinkles, hermit crabs, limpets.splash zone, which may receive only sprays of water during high tides (barnacles, lichens, periwinkle).To identify tide pool life, it helps to know the tide pool ecosystem has five different zones, and that individual plants, animals, and microorganisms have adapted to survive within the conditions in particular zones: wet-dry, dark-light, warm-cold, more or less saline (salty), whether favorable to reproduction, and degree of safety from predators.įrom highest and driest to lowest and wettest, these zones (and some of the creatures in them) are In town, look for marine life clinging to dock pilings and rocks at city waterfront parks, marinas, and along the Tommy Thompson Trail. The best Anacortes tide pools are at Sunset and West beaches in Washington Park (on Oakes Ave., just beyond the ferry landing) and at the southern end of Rosario Beach in Deception Pass Park (Discover Pass required). Tide pools are found along rocky shores where, when the tide goes out, pools of saltwater are left in depressions in the sand and rocks. To explore this fascinating world for yourself, pick up some picnic fixin’s or sandwiches at The Store Grocery or Gere-A-Deli and head for the shore. These wastes fertilize trees and plants that provide humans and animals with more food as well as with materials for shelter and warmth. Who eats the salmon? We do! And so do bears, who then leave salmon scraps-as well as bear skat-in the woods. Imagine this: microscopic algae in the water are eaten by small forage fish, which, in turn, are food for salmon. It’s here you’ll find essential links in the interdependent food web on which all life depends-including our own. Rather, look to the island’s perimeter to discover natural wonders hiding under rocks, buried in sand, and clinging to kelp in fascinating yet fragile ecosystems called tide pools. ![]() Some of Anacortes’s most valuable treasures aren’t found on Commercial Avenue or in the Anacortes Museum.
