best known organisms of near shore and tide pool habitats are the sea stars.<\/p>\n<p>Along the Oregon coast <em>Pisaster ocheaceus<\/em> is shades of purple, brown, and orange are found in many tide pools at low tide.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/07\/key-ss-a-1024x316.jpg\" width=\"1024\" height=\"316\" title=\"6b2 Tidal Zones\" alt=\"6b2 Tidal

killed massive numbers of pacific coast sea stars in this decade, and this had an unexpectedly significant impact on other tidal pool species.<\/p>\n<p>A <strong>keystone species<\/strong> has a disproportionately large impact on its community, even if it does not have a high biomass.<\/p> <p>Loss of sea stars caused the animals they ate to increase dramatically in number, and this effect cascaded through the food web, changing the community significantly.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/07\/key-def-999x1024.jpg\" width=\"999\" height=\"1024\" title=\"6b2 Tidal Zones\" alt=\"6b2 Tidal Zones\">\n[embed]https:\/\/vimeo.com\/469593671[\/embed]\n<p>This is a scan of a tidal pool at low tide.\u00a0 Note how dramatically different the organisms are lower on the rock where they are cooler and wetter.\u00a0 This is why it is worthwhile to plan a coastal trip using tide tables.<\/p>\n<p>You may have experienced reaching the tidal pools at high tide, when most of the rocky pools you want to explore are under water.\u00a0 Keeping an eye out for any possible sneaker waves, there can still be a lot to see in the higher pools.<\/p>\n[embed]https:\/\/vimeo.com\/311594957[\/embed]\n<img src=\"http:\/\/biotas.org\/wp-content\/uploads\/2020\/10\/b2-less-photo.jpg\" title=\"6b2 Tidal Zones\" alt=\"6b2 Tidal Zones\">\n<p>These high pools are warmer and often have freshwater mixed in with the saltwater.\u00a0<\/p>\n[embed]https:\/\/vimeo.com\/469380192[\/embed]\n<p>This is not the place for sea stars and anemone, but the brownish-green algae flourishes, supporting a unique food web.<\/p>\n<p style=\"text-align: center;\">It may take a moment to adjust your eyes to the smaller scale, but then you can see that life is everywhere in these small pools that most people walk right past.<\/p>\n[embed]https:\/\/vimeo.com\/469933890[\/embed]\n[embed]https:\/\/vimeo.com\/469934294[\/embed]\n[embed]https:\/\/vimeo.com\/469933518[\/embed]\n<p>Another option is to study the barnacles and clams on the high rocks, or enjoy the unique salt-tolerant coastal vegetation along the trails leading to the tidal pools.\u00a0 No trip is a wasted trip, there is always more to observe.<\/p>\n<h6 style=\"text-align: center;\">One hint: secure your quadrat with a string :).<\/h6>\n<img
