Velvet worm facts for kids
Quick facts for kidsVelvet worms
|A member of the Peripatidae family|
The two living families are the Peripatidae and the Peripatopsidae. They show a peculiar distribution, with the peripatids being mainly equatorial and tropical, while the peripatopsids are all found in what used to be Gondwana.
The segmented worm-like organisms have tiny eyes, "fur", antennae, multiple pairs of legs, and, slime glands. The group is thought to be related to arthropods. They prey on smaller animals such as insects, which they catch by squirting a sticky slime.
Possible fossil history
Fossils from the early Cambrian bear a striking resemblance to the velvet worms. These fossils, known as the lobopods, were marine. They were a clade from which arthropods, tardigrades, and Onychophora arose. They are found in the Cambrian, Ordovician (possibly), Silurian, and Pennsylvanian periods.
Historically, all fossil Onychophora and lobopods were lumped into the taxon Xenusia. However, few of the Cambrian fossils have features that definitely unite them with the Onychophora. The exceptions are Hallucigenia and Collinsium ciliosum, which have distinctly onychophoran-like claws.
