Psamathini

Psamathini are a tribe of phyllodocid "bristle worms" (class Polychaeta) in the family Hesionidae. They are (like almost all polychaetes) marine organisms; most are found on the continental shelf, but some have adapted to greater depths down to the abyssal plain.[1]

Genera

5-8, see text

Their dorsal cirri alternate, and they usually lack facial tubercles. Most have prolonged teeth on the chaetal blades. 5 genera are placed in the Psamathini with certainty, and three further ones are often included here too in recent times, to make this tribe refer to a distinct clade of polychaetes:[2]

  • Bonuania Pillai, 1965 (tentatively placed here)

gollark: There is also the question of what to have in the modpack.
gollark: I mean, if people actually want a server, I can host it on my stuff.
gollark: BigReactors is kind of boring, the reactors have weird rules and don't explode. There's Nuclearcraft, which is arguably more realistic, though.
gollark: https://www.archmission.org/spaceil ← interesting real-life implementation of pretty long-term storage
gollark: No, Intel stuff is affected by both, basically every modern one including ARM by spectre.
