The Philippine crocodile is endemic to the Philippines. Its scientific name is Crocodylus Mindorensis, after Mindoro, where the type of specimen was caught. It is a freshwater crocodile. It can grow up to three meters. Females construct a nest of grass, twigs and sand close to water and lay up to thirty eggs. After two to three months, the eggs hatch. Juvenile crocodiles eat shrimps, insects and snails. Adults prey on fish, birds, rats and snakes and occasionally on larger animals such as wild pigs and deer.

The Philippine crocodile is strictly protected under Philippine law. The Wildlife Act prohibits the killing, selling or keeping of the species. The Philippine government initiates a captive breeding program for the species. The University of Southern Mindanao has a crocodile conservation project in Ligawasan Marsh. The Mabuwaya Foundation and Isabela State University implement a project to preserve the Philippine crocodile in the Northern Sierra Madre Natural Park by educating people, protecting fresh water habitat and reintroducing the species in the wild.


For more than 45 years, WWF has been protecting the future of nature. The world’s leading conservation organization, WWF works in 100 countries and is supported by 1.2 million members in the United States and close to 5 million globally. WWF's unique way of working combines global reach with a foundation in science, involves action at every level from local to global, and ensures the delivery of innovative solutions that meet the needs of both people and nature.

WWF's mission is the conservation of nature. Using the best available scientific knowledge and advancing that knowledge where we can, we work to preserve the diversity and abundance of life on Earth and the health of ecological systems by protecting natural areas and wild populations of plants and animals, including endangered species;  promoting sustainable approaches to the use of renewable natural resources; and promoting more efficient use of resources and energy and the maximum reduction of pollution. 

We are committed to reversing the degradation of our planet's natural environment and to building a future in which human needs are met in harmony with nature. We recognize the critical relevance of human numbers, poverty and consumption patterns to meeting these goals. (
