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!:)
An illustration of a strange black fish on a white background. It has a big head with long, needle-like teeth emerging from its upper and lower lips, and the eye is very small. The fins have strange, branching rays, and a smaller, more traditionally-shaped fish hangs off its tail. Credit: Bertelsen via Fishes of Australia
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.
Itโs this time of the year again! Merry #fishmas ๐๐๐
#deepsea #fish cabinet! In the #evolution exposition of the National Museum of Natural History in Prague. It glows in the dark!!๐ (my primary goal was to see Lucy, the #Australopithecus, but thatโs a no photo zone:-)
New preprint!

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!!!๐ (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 Knฤลพnou, Czechia ๐๐๐.

Prof. Victor Ambros visited Charles Universityโs Faculty of Science, giving a packed lecture on โDevelopment timers in a tiny worm!โ ๐ชฑ followed by lively discussion ๐ฌ. A big day for science ๐ฌโจ

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 Advancesย ๐๐ง โAcquisition of neural crest promoted thyroid evolution from chordate endostyleโย โ check it out here: www.science.org/doi/10.1126/...
Endless thanks to the incredible collaborators who brought this project to lifeโyouโre 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!:-) ๐ฑ๐ฑ๐ฑ One of the gems found at a Taiwanese fish market: a tiny #lanternshark (Etmopterus). Some species mature at just ~20 cm - this oneโs head was thumb-sized๐:) Deep sea never stops surprising:-) #DeepSea #shark๐๐๐
We're hiring a postdoc!๐
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!

An amazing talk on mesophotic fish given by @kaithefishguy.bsky.social ๐ฑ at #IPFC12 in Taiwan. So many new records for Australia from the deep(er) sea๐
..and my favorite figure on deep-sea fish vision! ๐ 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 glow๐ด๐ต #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!๐ 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 ๐ฑ๐ฑ๐ฑ
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!๐๐๐

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:-). Thatโs the real impact!:-) hope it gets translated in Eng eventually:-)

GRC on Photosensory Receptors and Signal Transduction 2026 announced! www.grc.org/photosensory...
A Sigmops elongatus fish laid flat against a dark background. The colour is black with a slight silvery sheen on the flanks. Large light organs, associated with pale, pearly masses are arranged in rows along the underside of the fish. The mouth is large and curved, with sparsely-spaced, sharp teeth. The eyes are quite small and wedged right up front in the snout. A scale card with mm intervals and the words "Fish Time" printed on it indicates this fish is about 20cm long.
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!
