The ancient worm that fires jets of sticky slime to catch prey
This ancient little worm hunts by firing two jets of sticky slime like a net.
Which one is REALLY true about the Velvet Worm?
The short version
The velvet worm, nearly unchanged in 500 million years, hunts by squirting two whipping streams of sticky slime from nozzles beside its mouth, gluing prey in a net. It then bites in, injects digestive saliva to liquefy the insides, and even eats its own dried slime to waste nothing.

The full story
This soft little creature hunts by firing two jets of glue right out of its face. Meet the velvet worm, an ancient animal that has barely changed in five hundred million years. It creeps along the forest floor on dozens of stubby, squishy legs, looking almost like a caterpillar crossed with a slug. When it senses prey nearby, it aims two nozzles beside its mouth and squirts twin streams of sticky slime, whipping them side to side to cover the victim in a tangled net. The slime hardens in seconds, gluing the prey in place, totally helpless. Then the velvet worm strolls over, bites in, and injects saliva that turns the insides to soup before slurping it all up. It even eats its own dried slime afterward, so that nothing goes to waste. Follow for more weird animal facts.
The worm keeps its slime as a watery liquid packed with tiny protein blobs, stored in glands inside its body. To fire, it squeezes this liquid super-fast through two soft, floppy nozzles beside its mouth. No muscles aim the nozzles - the jet shoots out so fast that it makes the bendy nozzles flap on their own, which is why the slime whips side to side. As the flying threads stretch and hit the air, those protein blobs snap together into sticky, stiffening strands that harden into a tangled net.
