The velvet worm's strategy of hunting with rapid-fire slime cannons

The velvet worm's strategy of hunting with rapid-fire slime cannons

@Dr. Goo · June 29, 2026

The velvet worm looks like a squishy, velvet-covered gummy bear that couldn't hurt a fly. In reality, it’s a walking super-soaker filled with industrial-strength glue.

It hunts by firing twin slime cannons from its face. These nozzles wiggle so fast that the slime sprays out in a chaotic, crisscrossing net.

The goo hardens instantly on contact, turning into a stiff, sticky trap. It’s a total Spiderman move, leaving the victim paralyzed while the worm casually strolls over to grab a snack.

Wait, how does the worm avoid getting stuck in its own mess?

You'd think so, but this creature wears a permanent Teflon suit. Its skin is covered in millions of microscopic, water-repellent bumps that make it impossible for the glue to grab hold.

Even if a stray drop hits, it just beads up and rolls off like water on a waxed car. The worm glides right over its paralyzed victim without ever getting its own feet stuck.

And here is the ultimate cheapskate move: it eats the hardened slime net along with the prey. It is like a hunter who melts down his old traps to recycle them for the next meal.

Hold on, how do you even chew something that's basically superglue?

It doesn't just 'chew' it like gum; that would be a dental nightmare. Instead, this worm uses sharp, sickle-shaped blades inside its mouth to slice through the tough fibers.

Then, it spits digestive enzymes onto the hardened net and the prey, turning the whole 'glue-and-bug' combo into a liquid smoothie.

Once the trap melts, the worm slurps the soup back up. It’s the ultimate zero-waste lifestyle—reclaiming those expensive proteins to reload its cannons for the next hunt.

So it basically has tiny machetes hidden inside its face?

Nature really went for the 'Swiss Army Knife' aesthetic here. Those blades aren't actually teeth like ours; they are modified legs that migrated into its mouth over millions of years.

Imagine if your big toes moved up to your jaw and sharpened themselves into hooks just to help you eat. It’s a classic evolutionary glow-up—turning walking gear into stabbing gear.

These dual-claws work like a pair of bolt cutters, slicing through the prey's tough exoskeleton so the digestive spit can get to the good stuff inside.

Does it have enough legs left to actually move around?

It’s not exactly hurting for transportation. Depending on the species, these worms can rock anywhere from 13 to 43 pairs of legs. Turning two into 'mouth-knives' is just a minor business expense.

These aren't fancy, jointed legs like a crab's. They’re more like squishy, liquid-filled stilts. They move using internal fluid pressure—basically walking on a series of tiny, rhythmic water balloons.

It’s a slow, graceful stroll that makes them look like a very long, very soft bus. Even with the face-machetes, they’ve got plenty of spares to keep the hunt moving.
