Sisters find deadly Australian red-headed mouse spider rarely seen by humans in the Blue Mountains

Two sisters walking through the bushland have come across a rare red and black spider that has ‘abundant amounts of venom’ and can be as deadly as a funnel web.

Meg and Hannah Jefferson were out on a forest walk in Bilpin in the Blue Mountains on Saturday when they filmed the huge red-haired mouse spider crawling along a path.

The vision uploaded to social media shows the unusual spider with a bright red head, large fangs and huge legs scrambling across the rocky surface.

You can hear Hannah say in the video, “yuck, that makes me sick.”

Meg told Daily Mail Australia that she and her sister were shocked to see the huge creepy crawly.

‘It was unreal. It gave me and my sister quite a shock, I had never seen a spider with such a big red head,” she said.

The Australian Museum said females of these species can produce “abundant amounts of a highly poisonous toxin.”

It added that they were potentially as dangerous as the Sydney fcountless web spider.

The spider captured on film is believed to be a female, but their bites are rare and they are almost never seen by humans

The female spiders like to stay in or around their burrows.

Meanwhile, the images sparked mixed reactions on social media.

‘One of my favorite spiders. I like the blue and red color combination on the males,” said one fan.

‘I had an infestation of this on my lawn, it was horrible! I would have nightmares!’ another wrote.

“Bro’s just walking, he’s not doing any harm,” said a third.
