Creatures of nightmares: a giant spider is caught on camera eating a possum on the wall of a terrified couple's hotel room.

A couple was in a romantic getaway in the island state of Tasmania, Australia, when they witnessed a horrifying scene that'll likely stick to their memories for years.

Justine Latton and her Husband, Adam, stayed over in a hotel room at Mount Field National Park when they saw a giant huntsman spider eating what looked like a pygmy possum.

The colossal arachnid clung to the wall, clutching its prey and frightening its unsuspecting audience.

Never seen anything like that before, Latton and Adam were terrified, and they snapped a few pictures of the creature and shared them on Facebook.

One of the captions read:

"Possum-eating spider! Taken by my husband at a Mt Field lodge."

Speaking about the incident, Latton told Fox News that the creature was the biggest spider she had ever seen in her entire life.

She said:

"Pygmy possums are quite common up there (Mount Field), we reckon the spider probably just saw an opportunity and went for it!"

"It was one of the biggest huntsman spiders he'd ever seen. And Tasmanian Pygmy Possums are the smallest of the pygmy possums, I believe. This one was about the size of a large walnut."

Latton added:

"This occurrence is very unusual, I'm told. Huntsman spiders will sometimes take a small lizard or frog, but mammals are not their usual diet."

"They had to catch the pair and release them outside, in order to open the door! But no spiders were harmed in the relocation effort (too late for the possum)."

The huntsman spider, commonly found in Australia and other parts of the world, including the United States, has a 1-inch body and a leg span of up to 5 inches.

However, large species can have a leg span of up to 12 inches (30 centimeters). The spider's name comes from the way it hunts and kills its prey instead of using the web like most spider species.

Huntsman spiders are also the second largest of all spider species globally, after Goliath Birdeater, and they're the fastest.

In southern Africa, these species are known as lizard-eating spiders or rain spiders. They live under rocks, bark, and other infrequently-disturbed places in garages, sheds, or warehouses.

Though huntsman spiders are poisonous, they're not considered dangerous to humans as their prey consists of insects and other invertebrates, such as lizards. But you should be careful when you encounter one.
