Around 1,100 land vertebrate species can be found in the Philippines including over 100 mammal species and 243 bird species not thought to exist elsewhere. 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. Parts of its marine waters contain the highest diversity of shorefish species in the world.
