Description
These are some of the most primitive animals on Chrysaoris and were the ones that gave rise to terrestrial life. The order they belong to are called advanced polygnaths. Primitive polygnaths died out millions of years ago because of the multitude jaws the possessed which made them placid and ungainly. I will be posting more about there anatomy soon.Related content

I verry much like these concepts, although I do not think they should be classified together... most often, jawed animals (fig. 1 and 4) are not classified along with jawless animals (fig. 2 and 3).

Fig 3 has jaws like a cookie cutter shark along with a pair of crushing jaws on the inside but as they get older they become stationary and their jaws atrophy so they develop a vascularized plume very much like that of giant tube worm using chemosynthesis and specialized bacteria to help them turn compounds into organic molecules. So basically they are tube worms of chrysaoris but the stay in the clade of advanced polygnaths because of the I guess larval stage you can call it.
