Velvet worms are segmented animals with a flattened cylindrical body cross-section and rows of unstructured body appendages known as oncopods or lobopods (informally: stub feet). They grow to between 0.5 and 20 cm (.2 to 8 in), with the average being about 5 cm (2 in). The number of leg pairs ranges from as few as 13 (in Ooperipatellus nanus ...Enter the email address you signed up with and we'll email you a reset link.Lobopods are spaced consistent with a segmental nature, with eight plicae in each segment, demarcated by lines of papillae and depressions; terminal features such as claws are not preserved. The posterior of the animal, and thus the total number of body segments, and position of the anus and genital opening, remain unknown.

All lobopods are visible in full or in part, except that the left lobopods 3 to 6 are concealed beneath the body, as suggested by elliptical integumental folds above the leg insertions (e.g. Figs. 1b and 2a, f, g; Additional files 1, 2, 4 and 7) in a manner similar to that seen in Aysheaia (e.g. plate 10 and figure 62 in ).6.

Many cells, including animal spermatozoa, have whip-like flagella (literally latin for "whips") that thrash through fluid. Other cells, such as the amoebocytes of sponges, move by extending protuberances termed lobopods and transfering their contents into them. ….
