As of February 2025, velvet worms have had only two [[nuclear genome]]s sequenced.<ref>{{Cite web |title=Euperipatoides rowelli genome assembly Erow_1.0 |url=https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_003024985.2/ |access-date=2025-02-23 |website=NCBI |language=en}}</ref><ref>{{Cite web |title=Epiperipatus broadwayi genome assembly ASM2802345v1 |url=https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_028023455.1/ |access-date=2025-02-23 |website=NCBI |language=en}}</ref> These are of ''[[Euperipatoides rowelli]]'' (a [[Peripatopsidae|peripatopsid]]) and ''[[Epiperipatus broadwayi]]'' (a [[Peripatidae|peripatid]]). The first one is highly fragmented, while the second is less so, but still needs improvement.<ref name=":03">{{Cite journal |last1=Sato |first1=Shoyo |last2=Cunha |first2=Tauana J |last3=de Medeiros |first3=Bruno A S |last4=Khost |first4=Danielle E |last5=Sackton |first5=Timothy B |last6=Giribet |first6=Gonzalo |date=2023-03-01 |title=Sizing Up the Onychophoran Genome: Repeats, Introns, and Gene Family Expansion Contribute to Genome Gigantism in Epiperipatus broadwayi |url=https://academic.oup.com/gbe/article/15/3/evad021/7039704?login=true |journal=Genome Biology and Evolution |volume=15 |issue=3 |pages=evad021 |doi=10.1093/gbe/evad021 |pmid=36790097 |issn=1759-6653|pmc=9985152 }}</ref> Velvet worms seem to display [[genome]] gigantism, with the more complete assembly (E. broadwayi) having an size of 5.60 giga-[[base pair]]s.<ref name=":03" /> Around 70.92% of its genome are [[Repeated sequence (DNA)|repeat sequences]], something that contributes to the bulk of its size.
