Do you know about the world's most endangered species of crocodiles in the world? In this article, we will explore some fascinating facts about the Philippine crocodile, one of the two varieties of crocodiles that are indigenous to the Philippines.
Also known as the Mindoro crocodile, the Philippine crocodile (Crocodylus mindorensis) is a freshwater crocodile. Earlier, it was considered a subspecies of the New Guinea crocodile and had a flourishing population throughout the country, but since 2008 it is listed as Critically Endangered.
It survives only in certain islands of the Philippines, namely Luzon, Dalupiri, and Mindanao island. As per recent surveys, their population is about 100 in the wild today.
One fascinating characteristic of this crocodile species is that it eats more sick fish in its natural habitat than healthy ones. Thus it aids in improving the quality of the fish stock and balances the population of common fishes by preying on them proportionately. Read on to know more about this eccentric and endangered crocodile species.

Philippine Crocodile Interesting Facts
What type of animal is a Philippine Crocodile?
A Philippine crocodile (Crocodylus mindorensis) is a reptile and is also known as a Philippine freshwater crocodile. It is one of the two indigenous crocodiles found in the Philippines, the other being the Philippine saltwater crocodile (Crocodylus porosus).
What class of animal does a Philippine Crocodile belong to?
Crocodylus mindorensis belongs to the class Reptilia, order Crocodilia, family Crocodylidae, and genus Crocodylus.
How many Philippine Crocodiles are there in the world?
There are only about 100 Philippine crocodiles left in the wild today.
Where does a Philippine Crocodile live?
A Philippine crocodile lives in small tropical wetlands.
What is a Philippine Crocodile's habitat?
While their preferred habitat is small wetlands, this species of freshwater crocodile is also seen to dwell in shallow ponds and lakes, creeks, artificial water reservoirs, and mangrove areas. Sometimes they make burrows-like spaces in sandy river banks.
It is seen that their favorable habitats have a maximum width, an average flow velocity of water, and a minimum depth. The juveniles and immature Crocodylus mindorensis prefer lakes with vegetation at the edges, while the adults are common in lakes with ample open water.
Who do Philippine Crocodiles live with?
Typically crocodiles are social reptiles. Though they do not form any social groups, they are seen to inhabit areas in groups. A behavioral study carried out in Dunoy Lake reveals that, on average, the distance among Crocodylus mindorensis in their environment was about 20 meters.
In captivity, they exhibit aggressiveness towards each other. In the wild, no aggressiveness is observed in adults. However, juveniles show intra-specific aggressiveness.
How long does a Philippine Crocodile live?
The crocodile is said to live as long as 70-80 years. However, there is still a lack of data to ascertain an average lifespan.
How do they reproduce?
More research is needed to understand the reproduction system of Philippine crocodiles. It is common for the males and females of the species to have multiple mates.
The males of the species are sexually mature at 15 months and females at 10 months. The breeding season starts in the dry season, from December to May, and the eggs are laid between April to August.
In a year, the females can have up to three clutches.
There is a break of between four and six months between the first and second clutch. The average clutch size varies and is typically in the range of up to 33 eggs.
A study of a female and male Philippine crocodile in captivity reveals that at the time of reproduction, the length of the female is 1.3 meters, and that of the male is 2.1 meters. The incubation period of the eggs is 65-85 days.
In the wild, the nest is built by the female Philippine crocodile during the dry season. It can be a hole at the banks or a mound nest comprising dried leaves, soil, twigs, or a combination of both.
The nest is located at a distance of up to 21 meters from the water's edge.
Both parents take turns to watch and guard the nest. The eggs of these species exhibit dependence on temperature during incubation for sex determination which means the temperature at which the eggs are incubated determines the sex of the crocodile.
What is their conservation status?
There has been a sharp decline in its population due to the loss of habitat and unsustainable fishing practices like dynamite fishing. This species of Philippine freshwater crocodile is one of the most critically endangered crocodile species globally. In the IUCN Red List, it is categorized as Critically Endangered. Various measures are being taken for its conservation.

Did you know...
Karl Schmidt discovered this species of crocodile in 1935 on the island of Mindoro, and for years it was classified as a subspecies of the New Guinea crocodile. However, after Hall's paper in 1989, it has been recognized as a separate species.
It is also called Bukarot in northern Luzon island in the local dialect and Buwaya in the common Filippino culture.
The decline in its population is attributed to excessive hunting and habitat loss. In addition, the locals have a low tolerance for any crocodile species because of the other species of crocodile (Crocodylus porosus) known to attack humans.
How to save the Philippine Crocodile?
Several conservation measures are put in place in the Philippines to save this species of freshwater crocodile. It is protected in the Philippines by the Wildlife Act since 2001, and it is illegal to kill it in the country.
The Protected Areas and Wildlife Bureau is also responsible for protecting and conserving its habitat. The Philippines' Mabuwaya Foundation has also taken up several conservation and awareness programs.
It establishes sanctuaries and breeding facilities for these freshwater crocodiles through its Crocodile Rehabilitation, Observance, and Conservation (CROC) Project. In addition, it works with the local population to raise awareness and change the perception of these crocodiles.
Why must we protect the Philippine Crocodile?
It is vital to protect this wildlife species because it faces extinction without conservation efforts. In addition, these crocodiles have a role to play in keeping the ecological balance of the wetland ecosystems they live in and are critical to maintaining riparian biodiversity.
