A '''sea cave''', also known as a '''littoral cave''', 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(contracted; show full)

Sea cave chambers sometimes collapse leaving a “littoral sinkhole”. These may be quite large, such as [[Oregon]]’s Devil’s Punchbowl or the Queen’s Bath on the Na Pali coast. Small peninsulas or headlands often have caves that cut completely through them, since they are subject to attack from both sides, and the collapse of a sea cave tunnel can leave a free-standing “[[sea stack]]” along the coast. The Californian island of [[Anacapa
 Island|Anacapa]] is thought to have been split into three islets by such a process. 

Life within sea caves may assist in their enlargement as well. For example, [[sea urchins]] drill their way into the rock, and over successive generations may remove considerable bedrock from the floors and lower walls. You might not find a big variety of fishes.
