It's not common for one to encounter a python or a king cobra, two of Singapore's native and largest snake species.

But one visitor to Dairy Farm was lucky enough to see both, at the same time, tussling it out in a drain.

Fight

The visitor shared photos and videos of the epic clash between the two giant reptiles on Facebook on June 14.

The roughly one-and-a-half-minute video showed the two snakes locked in a deadly embrace, with the reticulated python half submerged in the drain.

Meanwhile, the paler-coloured king cobra had its jaws firmly locked on the python's body.

The king cobra whipped its body around several times, it tail lashing against the wire fence nearby.

The video ended before the victor of the fight was revealed.

The visitor shared that he returned to the same spot later in the afternoon, but the drain was flooded and both snakes had vanished.

Do not approach snakes

King cobras are one of the most venomous snakes on earth, and the longest of the venomous snakes, being able to grow up to 5.4m long.

The reticulated pythons is the longest snake in the world, and can reach lengths of up to 10m long. However, they rarely exceed 5m.

While cobras use their venom to immobilise prey, reticulated pythons on the other hand are non-venomous constrictors, and kill its prey by constricting it to death.

Reticulated pythons can be found in both urban and nature areas in Singapore, and the species is listed as least concern by the International Union for Conservation of Nature (IUCN) due to its wide distribution.

This is compared to the more uncommon king cobra, which is classified as vulnerable by the IUCN.

The National Parks Board advises members of the public who encounter snakes to remain calm and not approach them. These snakes are shy individuals and do not attack unless provoked.
