When you see a massive snake approaching you, wouldn't you want to move away quickly or perhaps even scream in fear? One man, however, stood still as a massive reptile crawled up his legs and towards his shirt.

A video, shared on Instagram on Tuesday, shows a snake taking off from the ground with its tongue sticking out and slowly towards the man’s shoes before trying to crawl up his T-shirt. Throughout the short clip, the man is seen standing still with no fear or panic.

The clip has since gone viral with netizens sharing their views.

"Snakes are not scary to me (some time ago I held a 4 m pythoness in my arms). But the poisonous ones worry me," one person wrote.

"Such a sweet baby, I love snakes so much," wrote another user.

"She thinks he's a warm tree lol," another person commented.

Some users identified the snake as a non-venomous reticulated python.

"The retics are probably one of the most aware/smart snakes out there," one person commented.

Reticulated pythons are the largest snakes in the world, growing over 20 feet in length. The largest recorded reticulated python in a zoological environment was 28.5 feet long and weighed about 320 pounds.

Mostly found across southeastern Asia, including the Nicobar Islands, Myanmar, Philippines, and Malaysia, these reptiles prey on birds and mammals, including large species such as deer or boar.

On the occasion of National Reptile Awareness Day 2020, International Business Times spoke to a snake catcher and asked him if reptiles can be good pets.

"Yes reptiles can most defiantly be kept as pets, one thing you should note before keeping reptiles is that they don’t require a lot of attention nor do they show you any affection, so if you want a reptile to be all cuddly with, it is probably not the pet for you. I personally keep a large number of reptiles, from snakes to lizards to geckos, and even venomous snakes as pets. If you have a passion for reptiles and wildlife, then reptiles defiantly make great pets," Joshua Castle, a snake catcher from Brisbane, Australia, told IBT.
