Agusan Marsh Wildlife Sanctuary is a protected area in the Philippines declared by the former President Fidel V. Ramos. The marshland acts like a sponge, as it is nestled in the midwaters of the Agusan River drainage basin. Within its lakes, several floating communities can be found. The sanctuary was home to the 20.24 feet (6.17 meter) saltwater crocodile Lolong, the world's largest captive crocodile. The Agusan Marsh covers the municipalities of San Francisco, Rosario, Bunawan, Veruela, Loreto, Talacogon and La Paz in the province of Agusan del Sur.
