Rare footage of a huge crocodile residing at Singapore's Sungei Buloh Wetland Reserve has been captured by a visitor.

Two videos of the reptile, estimated to be more than 2m, were put up on the Singapore Wildlife Sightings Facebook page on May 26.

The estuarine crocodile, which is native to Singapore, was seen swimming during high tide in the brackish waters at the wetlands.The two videos shot from the boardwalk, showed the moving crocodile up close.

Other crocodiles present at nature reserve

After the two videos were put up online, commenters marvelled at the proximity the footage was shot from, as well as the size of the crocodile.

The person who shot the video wrote that he saw other big crocodiles at Sungei Buloh Wetland Reserve.

This was in response to another visitor who claimed to have seen a baby crocodile at the reserve.

Rarely seen as they camouflage well

These crocodiles are known to camouflage well even in the day and are difficult to see because they are often submerged in water.

They also prefer to hunt at night, eating mammals, birds, monitor lizards, and carrion, which is the flesh of dead animals.

According to the National Parks Board, the species that is found in Singapore is also known as the saltwater crocodile.

It is one of the largest crocodile species in the world and can grow to more than 5m in length.

It has long snout and a broad, muscular tail with ridges.

During the day, crocodiles usually come onto land to bask in the sun as they are cold-blooded.

They can become aggressive and attack, especially when provoked, whether on land or in water.

They are also deceptively fast.

The species is internationally classified as endangered due to the destruction of its habitats, over-hunting for its hide and meat, and human persecution.

Visitors to Sungei Buloh Wetland Reserve are urged to follow the signs and stay on designated paths.
