Onycophora: Commonly called a Velvet worm, is not a worm or caterpillar as it may appear. Given their own Phylum they are considered a transition between true  worms and arthropods.
Besides antennae they have eyes, 14 to 43 pair of legs, bear live young (though some lay eggs) and capture prey by spraying a sticky liquid at prey from organs on the head. Found in the tropics, this specimen in Costa Rica. Image and Text Copyright Joe Warfel
