Onychophoran – velvet worm
Velvet worms are arthropod relatives so different from most other animals that they’re classified in their own phylum, Onychophora. Setting them apart is their “elastohydrodynamic squirt-system,” a mechanism they use to shoot a web of slime at their prey to immobilize them.
