A close-up, eye-level shot captures a section of a concrete or rocky breakwater at the ocean's edge. Gentle white-capped waves wash over the wet, textured surface of the large, flat rocks, which are separated by deep, narrow crevices. Several small, dark-colored crabs are visible; some are stationary on the rocks, while others scurry quickly across the wet surfaces and into the crevices. The water is clear, revealing parts of the submerged rock. The sound of waves is audible.
