Oceanic Oases: Mysterious Hotspots of Life

Countless marine animals frolic on the steep slopes of underwater vol-canoes. In many cases, several are rare species not found elsewhere. This is in part due to the fact that plankton clings to the wall and pro-vides the fish with food in abundance. This documentary shows several of these oases and also examines the impact dive tourism has and whether preventive measures can help.
