Bartolomeo Bove and his friend Juca Ygarape were diving in the Formoso River in Brazil back in July 2019 when they ended up close with the largest snake in the world - a Green Anaconda. It's a massive 'nope' from me.
In the clip the huge reptile, which was around seven metres (23ft) in length and weighed about 90kg, can be seen lying on the riverbed as the divers get nearer.
The footage then cuts to the anaconda getting a little bit too close to the camera while flicking out its forked tongue.

The Green Anaconda is pound for pound, the biggest species of snake in the world - they can grow up to a staggering 9.1m (30ft) and weigh as much as 250kg (550lbs).
They kill by wrapping themselves around their prey, constricting victims' breathing with their powerful bodies. They can also unhinge their jaws so they are able to swallow corpses larger than their own bodies. Sounds grim, eh? And yet this man Bove and his pal didn't think twice of swimming right over to get the perfect shot. Fair play.
The snake then appears to get bored of the divers and slithers away - but Bove decides to follow the creature to get some more footage.
Rather you than me, pal.
After all that, Bove's determination paid off and he managed to get some absolutely incredible footage of the creature.
