New study reveals spiders sometimes snack on snakes

Basel, Switzerland - Charlotte might have snacked on a snake or two! A new study shows that many species of spider will eat a snake when given the opportunity, and some spiders deliberately hunt snakes hundreds of times their size!

Size wasn't so important, according to the study, though spiders did prefer baby snakes that could easily be hunted or caught in a web (stock image).

This is the result of an analysis of 319 documented cases published in the Journal of Arachnology.

Spider researcher Martin Nyffeler from the University of Basel in Switzerland and his colleague from the University of Georgia, Whitfield Gibbons documented half of the incidents in the study in America, and about a third in Australia.

Nyffeler spoke with the SyFy channel's news source, SyFy Wire, and confirmed, "This was unexpected. I was also surprised that so many spider groups are capable of killing and eating snakes, and so many snake species are occasionally killed by spiders. That certain spiders can kill snakes over three feet long, and also some of the deadliest snakes in the world, was another surprise. All of this was unknown before."

According to evidence, spiders are able to kill and eat snakes that are over three feet long, but most have success hunting very young, newly hatched snakes.

Though snakes most often got caught in webs, certain types of spiders like tarantulas (Theraphosidae) would deliberately hunt snakes. SyFy Wire reported that it took just a few minutes for a Brazilian tarantula to kill a snake in a lab setting, using a combination of venom and powerful jaws. And in less than a day, the spider's venom had liquified the snake's organs and it had sucked the snake completely dry.

Nyffeler's research revealed that at least 11 species in captivity and 30 out in the wild were documented killing 86 different species of snakes, many of which were hundreds of times the size of the spider assassin.
