(1) While burrowing, caecilians employ concertina locomotion, lateral undulation, and vermiform locomotion.

(2) We have presented two models for the origin of the body wall musculature in vermiform bilaterians.

(3) Another phylum, the Pogonophora, are also vermiform animals with a trochophore larva.

(4) This mode of establishing the mesodermal musculature likely has occurred in small vermiform organisms.

(5) The Harpactacoida are primarily benthic evident by their vermiform (worm-shaped) bodies.
