Hey, stop touching my Velvet Worm.

Just to clarify taxonomically a Velvet Worm (Peripatus) is of the phylum Onychophora.
The comman species of Velvet Worm today are indeed grey and sorta furry. Hallucigenia sparsa is an extinct species of onchophoran that was particularily spiney and freaky looking.
