Protecting Terranea’s Tide Line Purple Sea Urchin, Strongylocentrotus purpuratus Jackknife Clam, Tagelus californianus Between the Tides Terranea’s coastline provides a rocky haven for many marine animals that only thrive in this ever changing tidal environment. A visit to our tide pools is your chance to take a curious glimpse into the ocean. This is a habitat that includes algae (“seaweeds”) and a kaleidoscope of marine invertebrates. That means strange critters without vertebral columns like sea slugs, anemones, seastars and shell- Dungeness Crab, Cancer magister fish. They are all so uniquely designed and so critical to the life in our coastal waters. Pounded by surf, revealed at times to the sun, submerged again in salt water, such is life in the Tidal Zone. This special home, to a colorful medley of marine life, reveals itself daily as the tide slips below 1.0 feet. In case you wondered, here in California we experience two high tides and two low tides, which are referred to as diurnal tide. Tide height itself is governed by the gravitational forces exerted upon the ocean by the sun and the moon. Although the sun is much larger than the moon, the moon is much closer to the earth and therefore exerts a larger influence over our tides. Sunflower Star, Pycnopodia helianthoides A Wet Web! California Pacific Coast Kelp, Macrocystis pyrifera Food webs describe the shifting of food energy from organism to organism. An example of a marine food web connection might begin with phytoplankton, the microscopic algae drifting in ocean waters. Phytoplankton and seaweed form the base of the ocean’s food web because they do not feed on marine wildlife. They use the sun’s energy to make food energy in a process called photosynthesis. Get covered by Kelp! During low tides a variety of creatures rely on the shade and moisture provided by blades of living seaweed. The collapsed blades become thick underwater forests as the water returns. These aquatic forests act as nurseries for some fish species and food for others. The rocks provide the anchor that this ocean algae needs to hold onto for the tidal ride. They do not have roots like land plants for penetrating soft ground, but instead are designed to be cemented to hard surfaces. While plants on land obtain nutrients from the soil, seaweeds get nutrients from surfaces in contact with seawater. Filter it First! Filter Feeders belong to another level of the marine food web and they include bivalves (two shells) like the California Mussel who filters the small particles of plankton and decomposing matter known as detritus from the water. Other members of the web get their food in a variety of ways. Grazers, such as limpets, chitons and turban snails methodically mow the algae and diatoms off the rocks. Giant Sea Anemones have special stinging cells that stun their prey while sea stars send their stomachs out to feed on mussels right in the shell. Scavengers like shore crabs simply pick up the leftover bits and pieces. Look, But Don’t Touch! T hese delicate web connections are numerous and most are very fragile. When viewing tide pools step in bare spaces free of seaweed and animals. Give birds and sea mammals, such as seals plenty of space, as they can be easily disturbed, potentially leaving their young to fend for themselves. Rockweed, Fucus gardneri Green Anemone, Anthropluera xanthogrammica Black TurbanSnail, Tegula sp. Buller’s Shearwater, Puffinus bulleri Heed to safety as you journey to the tide pools, you are entering an ever changing environment. Watch for slippery steps, tread lightly and pay attention to tidal flow and incoming waves. Photograph, sketch or ponder, but please do not disturb these protected plants and animals on the edge!
