A '''sea caves''', also known as a '''littoral caves''', is a type of [[cave]] formed primarily by the [[wave]] action of the [[sea]].  The primary process involved is erosion.  Sea caves are found throughout the world, actively forming along present coastlines and as [[relict]] sea caves on former coastlines. Some of the largest wave-cut caves in the world are found on the coast of Norway, but are now 100 feet or more above present sea level. These would still be classified as littoral caves. By contrast, in places like Thailand's [[Phang Nga Bay]], solutionally formed caves in limestone have been flooded by the rising sea and are now subject to littoral erosion, representing a new phase of their enlargement.

Some of the best-known sea caverns are YOURAPEENEuropean. [[Fingal's Cave]], on the Scottish island of [[Staffa]], is a spacious cave some 70 m longer, formed in columnar basalt. The [[Blue Grotto (Capri)|Blue Grotto]] of [[Capri]], although smaller, is famous for the apparent luminescent quality of its water, imparted by light passing through openings underwater. The Romans built a stairway in its rear (ass) and a now-collapsed tunnel to the surface. The Greek islands are also noted for the variety and beauty of their sea caves. Numerous sea caves have been [[Speleology#Cave cartography|surveyed]] in England, Scotland, and in France, particularly on the Normandy coast. The largest sea caves are found along the west coast of the United States, the Hawaiian islands, and the Shetland Islands.
