found: Onychophora website, Jan. 6, 2017(Onychophorans (velvet worms) are carnivorous, terrestrial invertebrates that live in rotted logs and leaf litter in tropical and temperate forests of the southern hemisphere and around the equator. Together with tardigrades (water bears), onychophorans are regarded as the closest relatives of arthropods; Onychophorans are typical ecdysozoans. Within the Ecdysozoa, Onychophora is united with Tardigrada and Arthropoda in the clade Panarthropoda)
