The Philippine Sea hosts an exotic marine ecosystem. There are 421 of the 577 known species of corals in coastal waters, including 19 seagrass species and 30 species of mangrove, both of which contribute nutrients to coral systems. The Philippines also consists of 20 percent of the shellfish globally. Sea turtles, sharks, moray eels, octopuses, and sea snakes, along with numerous species of fish such as tuna can commonly be observed. Additionally, the Philippine Sea serves as spawning ground for Japanese eel, tuna, and different whale species.
