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

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

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

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!

I have special worms this time. This week, after 5 years of looking for planarians I found Dendrocoelum which is not D. lacteum. It's most likely D. coecum, endemic planarian which was known in Central Bohemian valleys. They need further work, 3 blind species possible. Stay tuned ;] #InverteFest

#FlatwormFriday. Taenia pisiformis scolex. 4 suckers, calcareous corpuscles in parenchyma are visible under tegument. Nice muscle fibers in parenchymal tissue. Just tiny slice, in mm scale. 500x, H&E, several frames. Not my production, operator was somebody from T. Gerrard & Co, UK #parasitology

Little untold marine story. Those are most likely Rhabdocoela cocoons. No idea if those were left by single animal. Or it is coincidence or sign of gregarious behavior in microturbellarians which producing single capsule [such as Dalyelliidae family]. Questions! 200x. Intertidal zone of Catalonia

Reference needed in care for non-biological offsprings. I'd like to know more because parental care in glossiphonids is awesome even without this. I observed several glossiphonids with juveniles, including feeding in Helobdella stagnalis. On picture is Theromyzon tessulatum with juveniles.

Early #WormWednesday - it's a marine leech most likely from Piscicolidae family. Beautiful large specimen. Happened today at chmidtocean.bsky.social, catch it here www.youtube.com/watch?v=v8vE...
