A footage posted to the Nature Society (Singapore) Facebook group on 21 January shows a crocodile chilling on the walking path at the Sungei Buloh Wetland Reserve (SBWR) and eventually heading into the forested area.

The reptile is most likely an estuarine or saltwater crocodile (crocodylus porosus) which is a common species to Sungei Buloh.

Sungei Buloh Wetland Reserve is Singapore's first ASEAN Heritage Park. NParks warning signboards can found around the reserve informing visitors what to do when they encounter the animal.

It's common for trail runners and adventure seekers to come across potentially dangerous animals during their run in Singapore. So please bear in mind the following tips when running in any reserves and nature parks to be safe and at the same time respect the animals.

What to do if you spot an estuarine crocodile when running in the reserve?

• Stay on visitor routes at all times and do not venture off the paths.
• Should you spot a crocodile on the path, stay calm and back away slowly.
• Do not approach or provoke the animal.
• If you require assistance, call the reserve information centres at 6794 1401.
