When you're out on a boat, you would be glad to see marine life, right?
But what this person came across is both beautiful and terrifying.
Ng Ham Wei posted a video on Lure Haven, a Facebook page for fishing enthusiasts, and warned them about a crocodile sighting near the Causeway.
Ng said that his sibling's friend, who works as a coastguard, spotted and filmed a large crocodile swimming in the waters of Sembawang.
In the clip, the reptile appeared to be uninterested in the boat and continued to swim away from it.
Crocodile sightings are common in Singapore's waters.
