The velvet worms slime cannon mechanism is irreducibly complex :
it needs at least three different systems
1) weapon: slime pistol/gland which stores an adhesive which is what this slime is
2) ammunition: paralysing slime which only dries and hardens when ejected
3) targeting mechanism/ability
Each of these traits would not provide any survival advantage by their own , and have to appear fully functional, otherwise the mechanism does not work.
evolution is blind and would have to randomly generate each part, which in turn would need to provide a selection advantage to be passed to the next generation. I agree that it is possible, however it is very unlikely and there currently is no evidence that this happened. We can accept it on faith. Question for you, how would you falsify this.?

Pistol Shrimp sonic weapon - Weird Nature - BBC wildlife
The pistol shrimp’s claw is an extremely specialized construct that needs precision design in order to function. Of the millions of random mutations that might occur that would change the shape of a claw (a bump, indentation or protrusion of some sort?) there would be precious few that would have been ‘on the way’ to becoming a ‘sonic gun’ variant. Granting that evolutionists admit that beneficial mutations are rare, the point is; “What survival benefit would those small shape changes have conferred to the shrimp on the way to becoming a sonic claw?”
The shrimp also takes part in an interesting symbiotic relationship with certain species of goby fish. The pistol shrimp has terrible eyesight and cannot see predators approaching. Despite its formidable weaponry, the pistol shrimp is left vulnerable to attacks by fast predators that can take advantage of its poor eyesight. To overcome this difficulty, the pistol shrimp stays close by its symbiont, the goby fish. The shrimp rests its antennae on the goby’s body. When the goby sees a predator approaching, it warns the pistol shrimp by means of certain bodily movements which act as signals. When the shrimp feels these signals, it retreats, along with the goby, back into their mutually-shared burrow. This allows the shrimp to lay in wait to ambush the unwitting fish with its pressure-weapon without fear.
There is no way that this tiny marvel of engineering did not have a designer.
