This mainly marine Site curving around the eastern tip of Aruba comprises a limestone plateau, dry stream beds, a freshwater pond, dunes, beaches, and shallow and deeper marine waters. These feature sea grass beds, coral reefs and reef islets and relatively clean water; a high biomass of herbivorous fish can be found here. The shallow waters serve as a refuge for six dolphin species: common bottlenose, rough-toothed, Atlantic spotted, striped, spinner and Pantropical spotted dolphin. The latter two give birth here. Further offshore, where the water drops deeper and there can be stronger currents and more swell on the surface, long-beaked common and Risso dolphin, false killer whale, pilot, humpback and minke whales, and whale sharks have been observed. The Site provides significant benefits in terms of coastal protection, fishing and tourism (diving and snorkeling). It is subject to long-term monitoring.
