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 🔬✨

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/...

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!

i don't want it

I JUST NEED IT

TO BREATHE TO FEEL TO KNOW I'M ALIVE

An amazing talk on mesophotic fish given by @kaithefishguy.bsky.social 😱 at #IPFC12 in Taiwan. So many new records for Australia from the deep(er) sea😍

..and my favorite figure on deep-sea fish vision! 🐟 Most species have 1 rhodopsin tuned to ambient blueish light. The cryza & wild spinyfin? It has 38, covering the wider blue-green range! And dragonfishes gave up (+/-) blue vision to see their own red glow🔴🔵 #DeepSea #Vision

New review on deep-sea fish vision and the contribution of genomic and transcriptomic data. Part of the future special issue on vision in challenging environments in Functional Ecology:-). With @drfishvis.bsky.social in @funecology.bsky.social

Seeing in the deep: evolution of the opsin gene expression in Bermin crater lake cichlids https://www.biorxiv.org/content/10.1101/2025.02.28.640660v1

New preprint! Evolution of vision in cichlids from the crater lake Bermin, Cameroon. A case of young adaptive radiation with species in the deep to see more red -unexpected and opposite to other deepwater groups. Thks to coauthors!😍 Look how cool is the fish:-)

Loving deep-sea fish and molecular evolution?

We're hiring!:-) Looking for a motivated PhD student to join us to study evolution of vision & to explore limits of vertebrate eye in extreme environment. Deadline 15th March. Thanks for applying and sharing!

How cute!! This female sea devil has just 1,5 cm 😱😱😱
Triggered by the recent fascinating spotings of Melanocetus in Tenerife (blue pics), I digged in our past sampling photos to show how monsterous they are even in a small size!😍😍😍

When you buy an interactive kid book on the oceans - and you find the results of your research there (on how deep-sea fish see their world:-). That’s the real impact!:-) hope it gets translated in Eng eventually:-)

Vychází únorový Vesmír.
Tentokrát je hlavním tématem SKLO. Poznáte, co je na obálce?
Dále mimo jiné:
🔹 rozhovor se Zuzanou Musilovou @fishevo.bsky.social
🔹 jihomoravská mikrorefugia, v nichž poslední dobu ledovou přečkaly i duby nebo jasany

GRC on Photosensory Receptors and Signal Transduction 2026 announced! www.grc.org/photosensory...

On a related note to last night's rant, I dissected some elongate fangjaws (Sigmops elongatus) earlier this week. This species is a protandrous hermaphrodite - juveniles are male and become female later. Also, can confirm the teeth are v. sharp - I stabbed myself in the thumb and it hurt real bad!

Rybičko, proč máš tak velké oči? V PANTu v Ostravě jsme se se @fishevo.bsky.social ponořily v batyskafu do hlubin kolem tisíce metrů za beztrnovkama a spol, jednou dokonce až do 8836 za vůbec nejhlouběji zaznamenanou rybou. Skvělý otázky z publika,hezký reakce. Více v knize Zvířata v éře lidí...
