We found these three specimens of Felimare tricolor on a rocky and coralligenous bottom at a depth ranging from 45 to 50 meters. These animals are quite common in the Mediterranean and are also difficult to photograph and film with normal cameras due to their small size. What is striking in this video is the presence of at least three specimens in very few square decimetres that leads us to think that they are probably being reproduced.
