Early #WormWednesday is Glossiphonia which doing best job at being just perfect leech on this photo www.inaturalist.org/observations...

Worm World | DISBOARD: Discord Server List Wormy place for all worm taxonomists and worm fans. Doesn't matter what vermiform critter is in your radar, every worm lover is welcomed. We can also identify your findings if you have nice photo.

If you have Discord you can make worm rain there, we have taxonomists for few groups so it will be taken into ID queue. disboard.org/server/14331...

Yeah, there is plenty of undescribed species as well. We know them by sight but we need specimens for finishing of the job.

This is Umbotectum capitofalcatum, not Rhynchodeminae subfamily ;] Welcome in our planarian mess ;]

Don't. They may be bitter [freshwater planarians are]. And some bipallid have also mild amount of toxins. It's forbidden bacon.

Thanks for bringing it into visibility. Because it's not Umbotectum capitofalcatum. It's some other species, I need dig through keys a little.

Coloration like that is reason why I call Malaysian region 'land of gummy worms' ;]

Isn't it nemertean juvenile? There is thin structure which may be a proboscis and some opening is visible at anterior part. Not sure if it isn't prorhynchid juvenile [this group have similar structures as nemerteans] at same time. Stop at disboard.org/server/14331... , maybe somebody knows.

We will be there, catch us if you can. We will most likely bring some planarian things too. XVI International Symposium on Flatworm Biology events.gwdg.de/event/1168/o...

Hard to say anything from those pictures. How this happened is unknown, no description. Australia have terrestrial leeches from Haemadipsidae family. They are fine climbers. Check 10.4103/IJO.IJO_1453_24 tho, there are freshwater species which doesn't affecting mammals but were found in human eyes.

Planarian phoresy in practice ;]

Possible gregarines in Helobdella stagnalis whole mount. Next year I will pay more attention to this kind of parasites. I'm looking for them in planarians but no result so far. May be a sampling bias. They should be present in dendrocoelids which aren't our target. 🌿 #invertebrate

Molecular characterisation of the invasive terrestrial nemertean Geonemertes pelaensis: long and complex mitogenome and presence of NUMTs

This is not a land flatworm... it's a land nemertean!
In this new paper, we describe its complex mitogenome, report the presence of NUMTs, and even more! 🧪

After a long(ish) while, the reference genome for the #leech #Hirudo verbana is officially out!

Phagocata bursaperforata Phagocata bursaperforata from DeKalb County, US-GA, US on December 18, 2025 at 02:08 PM by junior_bartram

Early #WormWednesday is this rare pokemon, Phagocata bursaperforata from Georgia, USA www.inaturalist.org/observations...

Deep sea polyclads spotted again by
@schmidtocean.bsky.social in the Argentine Basin. Specimen have two clearly visible nuchal tentacles, falling under Stylochoidea then. Available at www.youtube.com/watch?v=NqnW...

To all current/future planarian enthusiasts:

The next installment of the North American Planarian Meeting will occur in June 2026 in Ithaca, New York. We welcome anyone who wants to participate, organized by me and Chris Petersen (Northwestern). Please share far and wide. napm2026.weebly.com

Alright, we decided for broader view of worm world in our little Discord server. Various folks working on various different kinds of worms so it was natural change. Planarians included.

Genus Spathula Spathula from Mount Field TAS 7140, Australia on November 25, 2025 at 02:39 PM by Justin Chan

Early #WormWednesday, because I want. This looks like one of rare Tasmania dugesiids, most likely Spathula genus. We don't see nice photos of these often.

Leech lovers have place to stay on Discord now. If you like everything what sucks stops in. It's small but nice place with taxonomic focus. My leech shenanigans are posted here as well. discord.gg/q75c89AuBD

Strigeid metacercaria shenanigans continuing. Cysts were isolated from Erpobdella octoculata leeches. Polarized for visualization of double-layered cyst wall. One cercaria got out of the cyst, received mugshot as well. Barcoding primers are on the way. #parasitology #FlatwormFriday #invertebrate

Now published and open-access:

Alright, these wasn't on my bingo list but I'm not so surprised. Nosema is known case in leeches. I wonder if those can do xenoma as well when case is developed to the extreme.

In warm regions I have my own bet, Platydemus manokwari had certain not very picky nematode species . I will wait in this case because depicted flatworm is invasive in colder European regions and not in endemic region of my nematode tip

If you wonder about those white dots here is close up. Those are ciliates from Urceolaria mitra complex. No Trichodina denticles in adhesive disc are present, there is denticulate ring instead of denticles. Diff-Quick, 40x objective.

I'm not dead. Just very busy. Not much of time for internet at those days. Some adult Dugesia gonocephala from recent Slovakia batch. #FlatwormFriday

Huge polyclad pancake sampled today at Mar Del Plata Canyon, Argentina by @schmidtocean.bsky.social. I didn't spotted any significant head features like any type of tentacles which are present in various polyclad group. Available at www.youtube.com/watch?v=ttYm...

Another bunch of deep sea polyclads from @schmidtocean.bsky.social Argentina dive 819. Longer ones are somebody from Boninioidea? Really not sure. Anyway, that canyon sediments and rocks are covered by them. Available at www.youtube.com/watch?v=kAxq... and www.youtube.com/watch?v=FJNJ...

Six of those Stylochoidea-like polyclads sampled today by
@schmidtocean.bsky.social at Mar Del Plata Canyon, Argentina, cca 2500 m. Fine large #polyclads, enough to fill few double wide slides. Good luck with future description of those. Available at www.youtube.com/watch?v=xg9N... #WormWednesday

Pleasure to identify with this quality of photos. Last DIC picture in this observation is beautiful. #WormWednesday 🌿 #invertebrate
