Our recent publication on opsin gene evolution in aquatic and terrestrial blennies 🐠 made the cover in @biologyopen.bsky.social Read the story here journals.biologists.com/bio/article/... @fishevo.bsky.social

Deep-water crater lake #cichlids lost red cones and kept only green cones in the #retina. We expected these #photoreceptors to be either true green- or modified red cones, but it seems that they’re sth in between! Wanna see more? Pls come to Pau’s poster P3.54 at #icn2026vancouver @neuroethology.org

Whole-genome duplication changed vision in common barbel? YES! Blue+purple cones developmentally switch #opsin ohnologs (=> 1 in larvae, 1 in adult). In red+green sensitive cones - both ohnologs coexpress (=> wider spectral sensitivity). Please come to poster P2.35 to see more #icn2026vancouver

Interested in weird and crazy #photoreceptor types - like “superrods” in some deep-sea fish?🤩 Happy to see you on Wednesday poster (PS3.45) session at #ICN2026 #ICN2026Vancouver @neuroethology.org

Made it to @neuroethology.org #ICN2026Vancouver meeting! Let the neurosciencing in all sorts of animals begin 🧠🧬🔬 @fishevo.bsky.social @wensungceph.bsky.social

We all know #mudskippers, the terrestrial gobies. But did you know that #blennies have evolved similar terrestrial strategy too? Pleasure to be part of the team checking their visual system:-)) #cool #fish 😍 journals.biologists.com/bio/article/...

what a lecture hall! #eed26

Go lamprey, go😍😍😍 (the stone is too heavy though:-)

Spawning is here!!:-) European common minnows in nuptial colours. They can turn really 😍😍🤗🤗(Kamenice river near Semily, Czechia. #fish that #are #cool :-)

European brook lamprey breeding season is currently on! Cool fish alert!😍 Soumarsky Most, Czechia #lamprey #spawning #fish

Fishes of Lužnice 2026:-) Student field excursion to show Czech fish fauna. We got 19 species (15 native + 4 introduced) this year😍

European pikeperch male guarding its nest made of a cleaned algae patch. Love is in the water😍😍 In the Thaya river, city of Breclav, Czechia.

Insterested in #rhodopsins and #evolution? Looking for a #PhD? We're offering a PhD position combining both - and in deep-sea fish!:-) From protein to genes & evolution (and back). Deadline soon:-) Thanks for sharing! More info: www.fishevo.com/phd-position...

We have three new PhD doctors in our group!😍😍😍 Last Monday, Monika, Gina and Dima defended their PhD theses. Wonderful day full of tropical fish evolution, fish hemoglobins and #fish vision! CONGRATULATIONS🥳🥳🥳 Thanks to everyone involved!!!

Ops(es)in(g) in Prague with an amazing bunch of researchers @fishevo.bsky.social @joostraeymaekers.bsky.social l @emiliapsantos.bsky.social & Marta Barulenga :)

Fun to write!:)

For our final day of #25DaysOfFishmas, we're going full weird. Today's bizarre, lonely little fish is the needlebeard seadevil, Neoceratias spinifer. This prickly little lady is the only member of the family Neoceratiidae, nestling within the larger deep-sea anglefish order Ceratoidei.

It’s this time of the year again! Merry #fishmas 😍😍😍

#deepsea #fish cabinet! In the #evolution exposition of the National Museum of Natural History in Prague. It glows in the dark!!😍 (my primary goal was to see Lucy, the #Australopithecus, but that’s a no photo zone:-)

New preprint! “Climate-driven specialisation in plant–pollinator networks peaks outside the tropics” Testing the long-debated latitudinal specialisation gradient using >3,400 quantitative networks (>110,000 interactions). Led by @saileesakhalkar.bsky.social and myself ☺️ doi.org/10.1101/2025...

Our Special issue on Visual Ecology in Challenging Environments is out: #coral reef & #deep-sea fishes, #reindeers on polar daylight, #bioluminescence, non-visual #pigments & life in dark caves. Happy to co-edit with Sara Stieb + thks to all contributors! See in Functional Ecology: buff.ly/z5AYxZQ

So many diverse cory catfishes!!!😍 (no longer all in the Corydoras genus). Fascinatingly, their color mimicry evolved in parallel across different "cory" lineages. Spotted at the aquarium convention in Rychnov nad Kněžnou, Czechia 🐟🐟🐟.

Nobel laureate 🏅 Prof. Victor Ambros visited Charles University’s Faculty of Science, giving a packed lecture on “Development timers in a tiny worm!” 🪱 followed by lively discussion 💬. A big day for science 🔬✨ 👉 1url.cz/TJV4P

FishEvo team at the #eseb2025 congress! We presented research on barbel, sturgeons, cichlids and deep-sea fishes. What a cool meeting and an inspirative atmosphere! Thanks everyone!

Excited to present our research on deep-sea fish vision at #eseb2025. Thanks everyone for coming to my talk!

Excited to announce that our new paper is now published in Science Advances 🚀🧠 ‘Acquisition of neural crest promoted thyroid evolution from chordate endostyle’ — check it out here: www.science.org/doi/10.1126/...

Acquisition of neural crest promoted thyroid evolution from chordate endostyle

Integration of neural crest cells into the endostyle developmental program promoted its evolution into the thyroid gland.

Endless thanks to the incredible collaborators who brought this project to life—you’re the magic behind it all @dayyapparaja.bsky.social @urrutiahugo.bsky.social @jakeleyhr.bsky.social J.Stundlova, T. Solovieva, T. Haitina, S. Sanchez @fishevo.bsky.social M. Martik and my great boss Marianne Bronner

I am happy to share a new review article, as part of a future special issue on vision in challenging environments, led by @fishevo.bsky.social and @drfishvis.bsky.social

Pocket shark alert!:-) 😱😱😱 One of the gems found at a Taiwanese fish market: a tiny #lanternshark (Etmopterus). Some species mature at just ~20 cm - this one’s head was thumb-sized😍:) Deep sea never stops surprising:-) #DeepSea #shark💚💚💚

We're hiring a postdoc!👀 Join us to explore the amazing world of (deep-sea) fish vision! We're looking for a curious researcher to work with histology, FISH, and even crispr! Apply by 14 July 2025. Thks for sharing! #PostdocJobs #DeepSea #FishVision #Evolution www.fishevo.com/open-postdoc...
