The Wildlife of the Philippines includes a significant number of endemic plant and animal species. The country's surrounding waters reportedly have the highest level of marine biodiversity in the world. The Philippines is considered as one of the seventeen megadiverse countries as well as global biodiversity hotspot. In the 2000 Red List of the International Union for the Conservation of Nature and Natural Resources (IUCN), 418 of the country's 52,177 species were listed as threatened.
The Philippines has among the highest rates of discovery in the world with sixteen new species of mammals discovered in the last ten years. Because of this, the rate of endemism for the Philippines has risen and likely will continue to rise.
There are 612 species of birds found in the Philippines, of which 194 are endemic, 3 have been introduced by humans, and 52 are rare or accidental. There are 67 globally threatened species. These include the rufous hornbill and the critically endangered national bird of the Philippines, the Philippine eagle.
There are more than 111 species of Amphibians and 270 species of Reptiles in the Philippines, 80% of the Amphibians are endemic and 70% of the Reptiles of the Philippines are also endemic. It is believed that there are not more than 14 of the 114 total species of snakes in the country are venomous. Several species of reptiles and amphibians remains undiscovered. Unfortunately, several of these species were believed to have disappeared without ever being discovered. The Philippines also has 50-60 endemic Platymantis frog species, by far the most diverse genus of amphibians in the archipelago.
The endemic freshwater crocodile Crocodylus mindorensis is critically endangered and is considered the most threatened crocodilian in the world. In 1982, wild populations were estimated to be only 500-1,000 individuals; by 1995 a mere 100 crocodiles remained living in the wild. The recent discovery of a population of this species in the Sierra Madre mountains of Luzon brings new hope for its conservation. Projects were being made in an effort to save the crocodiles. The Crocodile Rehabilitation, Observance and Conservation (CROC) Project of the Mabuwaya Foundation is active in carrying out such projects.
