Mohéli National Park, located on Mohéli Island in the Comoros, encompasses 643.62 km² of marine, coastal, and terrestrial areas. Established in 2001 as the first protected area in the Comoros and upgraded to a national park in 2010, it was expanded in 2015 to cover nearly three-quarters of the island's land area. The park's marine section features a fringing reef, lagoons, mangroves, and seagrass beds, supporting species like coelacanths, humpback whales, and various turtles. The islets within the park are key breeding grounds for seabirds, while the rugged terrestrial landscape is home to unique species, including the Moheli scops owl and Livingstone's fruit bat. The park also protects Lake Dziani-Boudouni, a freshwater crater lake, adding to its biodiversity.
