These semi-dark caves correspond to vertical, shadowy overhangs or entrances to caves that are more of less exposed to light. The environmental conditions of these dark caves are very specific and can be similar to those of areas very deep in the sea. A diverse range of organisms can be found here, that change according to the specificities of each cave: water stagnation or the presence of currents, water temperature, etc. To meet these special living conditions organisms who live here have developed sometimes exceptional particularities. Many rare species can be found here that either endemic of that usually live in deep waters.
