This is the horror movie moment a camper switches on a torch at night to see a giant rainforest spider crawling across the other side of the tent canvas.

Bruno Ross caught the chilling moment on video as the 20-centimetre (7.9-inch) creepy-crawly walked over his shelter tent while he was camping out in Brazil.

Bruno was spending the night under canvas on Mestre Alvaro Hill, a forest trail in Espirito Santo State, on 24th March.

His footage shows how powerful torch lights up the canvans to show the huge shadow of the spider as it crawls slowly across the outside of the tent before the clip ends.

The spider is believed to be a huge wandering, or armed spider, said to be one of the most deadly to humans.

Medics say its danger is not only because of its size but because it injects massive doses of venom with its bite.

Bruno, 37, told local media: “Around 3:30 in the morning I got up to enjoy the view from the top of Mestre Alvaro, a view that is above the clouds.

” I opened the zipper of the tent and sat inside with just my head and hands out, I did some videos and took some photos.

“About 20 minutes later, I went to get my portable charger when the light from the flashlight hit the tent canvas, and the shadow of the spider appeared, an armoured spider measuring about 20 cm or more.

“I recorded it with my mobile phone, I put my boots on and left the tent, and with a piece of stick I picked it up and released it into the forest.”

Biologist Emanuel Giovani Cafofo said that when wandering spiders feel threatened, they can jump up to 40 centimetres (nearly 16 inches).

He explained: “It is common to find them in the forest, in urban areas it is rarer because they prefer forests, but nothing prevents them from appearing in places close to the riverbank.

“It is known for being one of the largest species of spider, especially of adult size.

“The recommendation is to always stay away from the animal or ask for help.

“But if the person feels safe, they can push the spider away with a branch to avoid any type of contact.”
