The video was recently shared by the University of MI, and it contains a sight no arachnophobe wants to see - a young possum completely covered by a huge, hairy tarantula, which was spotted easily dragging it back to its den.
Just when you think you've seen it all, a team led by University of MI biologists captured shocking video of a massive tarantula dragging a small opossum around the forest floor in Peru.
You can read the researchers' full paper, published last month in the journal Amphibian & Reptile Conservation, here.
"A surprising amount of death of small vertebrates in the Amazon is likely due to arthropods such as big spiders and centipedes", said University of MI evolutionary biologist Daniel Rabosky. "A surprising amount of death of small vertebrates in the Amazon is likely due to arthropods such as big spiders and centipedes".
"The opossum had already been grasped by the tarantula and was still struggling weakly at that point, but after about 30 seconds it stopped kicking", the paper's co-author Michael Grundler, a PhD student said in a statement.
Although numerous encounters were brutal, the team said by far the most vicious and terrifying is that between the tarantula and the mouse opossum.
Grundler's sister Maggie pulled out her cell phone and shot photos and some video, the statement said.
They watched for about five minutes and were able to document the moment on video, before the spider hauled its prey behind a tree root to enjoy its meal in peace.
Among their finds is a one-of-a-kind event when they chanced upon a large tarantula preying on a young mouse opossum.
The Michigan researchers captured footage and still images of battles between spiders, snakes, scorpions, ants, beetles, water bugs, among others. To do this, they carried out night surveys by walking through the forest with flashlights and headlamps and scanning the foliage for signs of activity.
"We were pretty ecstatic and shocked, and we couldn't really believe what we were seeing", said Grundler.
He brings a group of researchers to the lowland Amazon rainforest in a remote part of southeastern Peru once or twice a year.
Knowledge of predator-prey interactions between spiders there, however, remains somewhat limited given the diversity of prey and arthropod predators.
Arachnologist Rick West said tarantulas typically prey on frogs, but added: "They are opportunistic feeders and they'll take whatever they can subdue". "But it is a special human bias that leads us to think that this is somehow freakier than many other ways of dying: there is nothing pretty about most predation, whether it is coming from lions or peregrine falcons or crocodiles or anything else".
