Marine biologists make a difference between caves and caverns or over hangs. Adventure, rather than the flora or fauna, is the attraction of caves. The further into a cave you go, the less current or light passes through and the m (BOROVNIK, MANA CAVE, KORNAT EAST e.g.).

Over hangs go partially deep into the rock and offer also beginners in shallower depths the full color scale of the Mediterranean Sea (DOME, SMOKVICA, KAPRIJE e.g.).
