These creatures are actually in their own phylum and are not related to anything else. They look like a slug with legs but have the skin texture of a soft caterpillar. They like to live in rainforests in dark humid places, but the most amazing thing about them is that they hunt unlike any other predator. They are extremely slow moving but like to eat small invertebrates, so the way they hunt is they actually shoot sticky goo which their prey becomes entangled in. The goo hardens within seconds and the prey is stuck there. It's like Spiderman! Then the velvet worm can take its sweet time crawling over and injects its prey with toxic saliva that liquifies the prey's insides. the velvet worm then sucks it out.
