Members of the class searching for organisms in the surge channels of the exposed lower tidal region. While examining the intertidal regions, the class identified and classified the organisms that were found. Students carefully examined each low tide organism that was found and shared the discovery with classmates. The students found many organisms in the tidal pools, hiding in surf grass or under ledges of the rocks.
Students inspect a rock that is covered by a multitude of barnacles.
A group of classmates studying the soft rock substrate of the lower mid-tide region. Since Bird Rock extends above ocean level, the class was able to examine all the intertidal regions very easily. The mid-tide boulder field harbors a wide variety of taxa. The urchin is found under the boulders of the mid tidal rocks and may inhabit rounded burrows or depressions in the rock. When the tide is low, the species Stenoplax conspicua is found tightly clinging to the rocks and boulders of the middle tidal region.
