A sea cave is a natural formation created by the erosion of coastal rock by waves and water. These caves are typically found along cliffs and shorelines, where the constant movement of the ocean gradually wears away the rock, creating hollow spaces. The size and shape of sea caves can vary greatly, depending on the type of rock and the strength of the waves. Many sea caves are home to unique ecosystems, supporting various marine life such as sea urchins, crabs, and anemones. Some sea caves also feature stunning geological formations, including stalactites and stalagmites, formed by mineral deposits. These caves can be explored by boat or kayak, offering a glimpse into the beauty of coastal geology.
