“A marine ecosystem can be defined as the geographic area (of any size), composed of communities of organisms and their environment, where biological and energetic interactions are greater within than with adjacent ecosystems”.
The STP archipelago has a large maritime territory of 160,000 km2 and holds two ecologically and biologically sensitive areas (EBSAs): The Tinhosas Islands, which provide an important nesting habitat for more than 300,000 migratory seabirds but also attract essential marine megafauna and Equatorial Tuna Production Zone that is important to the life cycles of several large, commercially valuable, pelagic and migratory fish species. Also noteworthy are the presence of species such as: Hammerhead Shark, Sol Mola Fish, Whale Shark, Manta Rays; and the presence of five of the seven species of sea turtles in the world, including four that nest on the islands' beaches.
The islands are ideally located for fish diversity: close enough to the African continent to support fish species typical of the shelf region, but also with a narrow shelf separated by seas over 1500 m deep that provide coastal habitat for several fish. In addition to these factors, several currents contribute to coastal upwelling and to the biological productivity of highly migratory deep-sea and deep-sea fish species.
