The Celebes Sea is a marginal sea of the Pacific Ocean located between the islands of Sulawesi (formerly Celebes, Indonesia), Borneo (Malaysia) and Mindanao (Philippines). This marginal sea, also called the Sulawesi Sea, borders the Pacific Ocean to the east, the Philippine Sea to the northeast, the Sulu Sea to the north, and the Java Sea to the southwest. To the southeast is the Molucca Sea. The Celebes Sea has an average depth of 3,291 meters, reaching 6,220 meters below the surface at its deepest point. Part of an ancient oceanic deep sea basin, the sea is characterized by a diverse fauna and flora with whales, dolphins, manta rays, sea turtles, barracudas and several hundreds of coral species.
