Photographs showing a giant crocodile attacking a monitor lizard and then feasting on it recently went viral.

The images were taken by William Ko, a visitor at Sungei Buloh Wetland Reserve in Singapore on Saturday night, local news outlet Mothership reported.

Ko shared a series of five photos in the Facebook group Nature Society (Singapore). He wrote on the post that the "chonky croc" was chilling out in the sun before attacking. The crocodile then spotted the monitor lizard and lunged at it.

The massive reptile "bashes and smashes the monitor lizard until it literally breaks apart into smaller, easily swallowable pieces," wrote Ko.

In the photos, the crocodile appears to be swinging and whacking the monitor lizard against the ground of the wetlands.

The images, which may be disturbing to some viewers, were liked by thousands of users on Facebook. Some users praised Ko for the clicks, saying that witnessing this was a "chance of a lifetime." Others were amazed by the wildness of the wildlife.

"Wow, truly a force of nature. Did it do any ‘death roll’ maneuver? Sounds quite scary to witness though," one user commented. Another wrote: "William Ko it must have been a great feeling to be able to see n capture those moments ya...lucky you!"

While in this instance, the crocodile attacked the monitor lizard, recently there have been several incidents where the huge reptiles' encounter with humans turned tragic. Last week in Zimbabwe, a crocodile attacked and killed a 26-year-old man while he was trying to cross a flooded river. The victim, identified as Nebart Doro, was accompanied by his friend when the attack occurred. The victim's friend said the crocodile approached and leaped on the man. Police spent the day scouring the area around the river's course to find the victim's body. Local police then issued a warning to the citizens, asking them to avoid crossing the flooded rivers.

In another incident last month, an 8-year-old boy was mauled to death by a crocodile while swimming in a river in Malaysia. The incident took place in Kota Kinabalu, the capital of Malaysia’s Sabah state.
