I came here hoping to read more about this worm and its slime guns but no one did much yet so i had to look it up and now I've become the commenter i hoped to find? I hope the mildly interested people following after me find this cool:

The slime is incredible stuff. It leaves the worm’s nozzles as twin streams of sticky liquid. But once it touches the target, it hardens almost immediately into a stiff, hard gel that is neither sticky nor soluble in water. It’s an incredible transformation and for the prey, it’s a fatal one. By ‘milking’ an Australian velvet worm called Euperipatoides rowelli and studying its slime, Haritos has discovered that its properties come from a special type of chaotic protein.

Chaos Bolt! Man this worm is cool.
