On the concrete slabs at the edge of the water I have encountered are roaches centipede like insect that are called Ligia occidentalis also known as Western Sea Roach. They are identified by their very long uropods that are nearly half as long as the body. They hide most of the day in crevices or under stones just above the high tide line. They are considered scavengers, and feeds on microscopic algae in the upper-intertidal zone and supra tidal splash zone. Another observation I have found in the cliff tops of Sunset Cliffs Regional Park that is California native are Rosa arvensis also known as Field Rose. This beautiful flower have rounded to oval fleshy hips that enclose the seeds that attracts birds and small mammals. In addition Many insects, including bees, moths and butterflies are attracted to the Field Rose.
