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...
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 🧪 #parasitology
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! 🧪 doi.org/10.1038/s415...

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. 🌿 #invertebrate #taxonomy #discord disboard.org/server/14331...

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. www.inaturalist.org/observations...

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

Jean-Lou Justine@jean-lou-justine.bsky.social · 10mo agoOur upcoming paper explores the hidden world of parasites infecting invasive land planarians — yes, even invaders can have their own invaders.🧪 Out in just a few days. Stay tuned for some fascinating parasite stories! www.parasite-journal.org
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

This is so FREAKIN’ COOL! This calanoid copepod has a friend visiting…INSIDE ITS BODY!! There’s a trematode worm, a parasite, taking up pretty much every micron of this poor dude. You can see the worm’s suckers that is used to attach to its host. AWESOME!! 🦑 #plankton
Mothership of Dendrocoelum lacteum found today. We need some for our DNA barcoding shenanigans so I left my den for unexpected fieldwork today. Temperatures were rather hostile but worms are just fine. #WormWednesday 🌿 #invertebrate
Theromyzon tessulatum from weekend fieldwork session. This one had one epistylid epibiont, other glossiphonids had none. Weird, this locality is usually quite reliable on epistylid abundance. #WormWednesday 🌿 #invertebrate

Alboglossiphonia sp. from latest fieldwork session adding another finding of epistylid epibionts into collection. Case from 2023 is available on bioosm.brmlab.cz/histolka/pro.... Perhaps it's just about looking around. #WormWednesday 🌿 #invertebrate

Riutort’s Lab@riutortlab.bsky.social · last yr.Happy to announce the publication of our paper on Dugesia planarian species from Corsica and Sardinia that reports the first demonstrated case of hybridisation for this group using RADseq data @irbio-ub.bsky.social @geneticsub.bsky.social @molevolub.bsky.social authors.elsevier.com/c/1ktMS3m3nN...
Me: OK, we need check this on other planarian, let's see Girardia tigrina Brain: OK Brain: Isn't it nematode in the pharyngeal tissue? Me: It is,but later Brain: I wanna nematode! Let's check all slides! Me: No, it's 16 slides, back to original task! Brain: I wanna nematode! Me: OK, but I hate you.
