Finally, we tried to tide up the mess in the nomenclature on this part of spiralian tree. We systematize different naming systems and proposed to exclude Chaetognatha from Gnathifera and instead use Chaetognathifera to refer to the earliest branch of Spiralia. (3/4)

Platyzoa: Platyhelminthes, Gastrotricha, Gnathifera
Lophotrochozoa: Trochozoa, Lophophorata, Gnathifera

Our manuscript reconsidering Chaetognath position is out, a redefined Gnathifera together with spiralian branching discussion, with Katja Peijnenburg (who took this lovely picture of Pterosagitta draco) and others.... cell.com/current-biolog… Current Biology

Finally out, our first paper on #neural development of the chaetognath Spadella:

I am such a big fan of this double page spread.

Morphology of Nanaloricidae and Pliciloricidae in Schmidt-Rhaesa 2013 (Handbook of Zoology - Gastrotricha, Cycloneuralia and Gnathifera).

Loriciferans are just excellent.

Another potential stem lineage Gnathifera - very interesting! A possible Cambrian stem-group gnathiferan-chaetognath from the Weeks Formation (Miaolingian) of Utah cambridge.org/core/journals/…

No-bilaterales, Spiralia, Gnathifera, Panarthropoda, Xenacoelomorpha fuera de protóstomos y deuteróstomos... Hay que ser tonta para ver este índice y sonreír. Pero es que me encanta el nuevo Brusca 😊!

#ArrowWorms aren’t exactly worms or fish, but instead occupy a group called Gnathifera, or “jaw-bearer.” Though this creature only has simple eyes, it is a master hunter of #zooplankton , sometimes referred to as “tiger,” in the #OceanTwilightZone . (📸: Paul Caiger, © #WHOI )

そういえばこれの論文そろそろ出ないかな
ネクトカリスは頭足類じゃなくて担顎動物 Gnathiferaに属するっていう話（最近の論文doi.org/10.1080/147720…に従うとChaetognathiferaが正しいけど）

𓆨Luke A Parry𓆨 Spiralia. As Ferdinand Marlétaz points out, if Gnathifera (including chaetognaths) branch first, then neither lophophore nor trochophore are ancestral for the clade, but spiral cleavage could be since gnathostomulids might have it. (if they don't: Gnathospiralia)

早くもフランス語のwikiでは担顎動物のページにアミスクウィアの顎構造の話とヤムシとの関連性も追加した図まで作成されてました。
参考が(Vinther, 2019)の方なので復元が異なります。

Wow! 'Collectively, our results support an inclusion of chaetognaths in
gnathiferans and Gnathifera as sister group to remaining spiralians' x.com/biofunch/statu…

And here is another super cool one, on the Cambrian Amiskwia which does not nest within Gnathifera, but is closer to arrow worms. Also🥂 to the newly recovered 'Gynognathifera', an apparently female powered clade😅
