similar to ones found on gnathostomulids, but up to three cilia may arise from a single cell in L. maerski, while gnathostomulids never have more than one...

it fell in the stem lineage of any extant phylum then it would be a gnathostomulid. A 2022 study supported a stem-chaetognath interpretation, suggesting...

Although the absence of a coelom also occurs in other bilaterians: gnathostomulids, gastrotrichs, xenacoelomorphs, cycliophorans, entoproctans and the...
