Caterpillars might not be the first creature to pop into your head when you imagine venomous creatures, but this one has one of the most painful bites known to man. It’s not only highly venomous, but new research has revealed it evolved its venom with the help from some tiny, little friends.

00:00If I asked you to close your eyes and picture a venomous creature, what would you come up with?
00:08One of these? Maybe even this?
00:10Well, according to researchers from the University of Queensland in Australia,
00:14this guy is not only highly venomous, but new research has revealed it evolved its venom
00:18with the help from some tiny little friends.
00:21This is a caterpillar, or the larva of what's commonly called the flannel moth.
00:25According to the new study, toxins from bacteria could be responsible for having aided the development
00:30of the creature's painful stings via a process called horizontal gene transfer.
00:35The caterpillars actually sting via venomous spurs hidden beneath their luxurious coats.
00:39According to the researchers, it's so painful it's been described as walking on hot coals,
00:44or the worst pain a patient has ever experienced.
00:47While researchers were investigating why it was so painful,
00:50they noticed it was quite different from other venomous caterpillars.
00:52It works in a very similar way to bacterial toxin, binding to a cell's surface,
00:57and eventually ripping holes in it, with the researchers concluding the bacteria must have passed it along,
01:02writing,
01:02The venom in these caterpillars has evolved via the transfer of genes from bacteria more than 400 million years ago.
