- In the video the Malabar pit viper is slithering along the river rocks as a king cobra approaches and sinks its fangs into the Malabarβs neck.

Pit Vipers β A Highly Evolved Venomous Snake
Pit vipers are no push over! They range in size from snakes like the littleΒ massasaugaΒ (which grow up to about 30 inches) up to the hugeΒ bushmasters (which can reach 12 feet). The snake here is described as a Malabar pit viper which grow to around 41 inches.

They are all venomous but have different types of venom that contains different types and quantities of chemicals. Some venom is more dangerous than others.
However, they all have hollow fangs through which the venom is delivered into their victim. When they attack, they plunge their fangs into the prey and venom travels from the venom glands at the rear of their heads, through the fangs and into the flesh of their chosen prey. Pit vipers are also themselves prey. They are hunted by other snakes including indigo snakes,Β king snakes, and, as we see here, the king cobra.
King Cobra Hunts a Pit Viper

The footage was published online by the King Cobra Conservancy project. Their mission is to βsupport ecological research and conservation initiatives aimed at determining the status of King cobras in the wildβ. It was shot by volunteers at the ARRS King Cobra Telemetry in India in a 10 acre plot in a jungle clearing.
King cobras prefer habitats that include streams, forests, bamboo thickets or swamps where they can reach up to 20 years of age. They are a very impressive snake. In fact, their venom is sufficient to kill an elephant so it is not surprising that this pit viper succumbs so easily. They are also unique snakes because they build a nest to lay their eggs in. King cobras are the largest venomous snake in the world and can grow up to 13 feet in length!
Is This Normal Behavior?
Yes, it is common for king cobras to eat other snakes. In fact snakes are at the top of their food list, followed by lizards and sometimes small mammals like rodents and birds. If presented with the same type of snake as meals, king cobras may even develop a taste for a specific kind of snake, like Indian cobras or vipers, and seek those out.
