Why are some species smaller than a paperclip while others grow longer than a school bus? How is body size evolution governed in animals? Out now in @pnas.org we tackle these longstanding questions through a genetic lens using my favorite group of fishes as our model!! www.pnas.org/doi/10.1073/...

Meet the mesmerizing new addition to our Into the Deep/En lo Profundo exhibit, rough snailfish! These ethereal charmers live in the benthic zone, a scientific term for the seafloor.

Update of our preprint on Inter-individual gene expression variability in fishes! We improved statistical analyses of continuous variables, and especially added machine learning on promoters which confirms cis-regulation of organ-specific expression variability.

Inter-individual gene expression variability implies stable regulation of brain-biased genes across organs

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

An (omics) perspective on the evolution of vision in deep-sea
fishes reveals exceptional adaptations to life in the extreme

Musilova & Cortesi 2025 Functional Ecology

besjournals.onlinelibrary.wiley.com/doi/pdfdirec...

#ichthyology #teamfish neat review of genetics of deep-sea vision in fishes
deep-sea adaptations have evolved independently in several groups. Eye shape: A prominent morphological example is the evolution of an elongated tubular, barrel eye to maximize photon capture in several deep-sea groups. Groups, where tubular eyes are common, are marked by a black square and a tubular eye scheme; groups with one/ few cases of tubular eyes but where the majority of species have a camera-type eye are marked with black dots (i.e. anglerfishes and dragonfishes). Retina: Rod-only retinas are a common feature of many adult deep-sea fishes. In other cases, they possess the typical duplex retina with cones (green cells) and rod cells (grey cells). Multibank: In some species, the rod cells are organized in multiple layers, forming a multibank retina, while other deep-sea fishes have the typical vertebrate single layer. Cone/rod id: Some deep-sea fishes have photoreceptor cells with an uncertain id that is intermediate between rods and cones due to a mismatch of the opsin and phototransduction cascade genes (e.g. in Scopelarchidae and Evermanellidae; Aulopiformes), or thanks to the presence of transmuted cells (i.e. rod-like cones in Maurolicus spp.; Sternoptychidae; Stomiiformes). Rhodopsins: Like other vertebrates, most lineages only have one rhodopsin (rh1) gene. Two rhodopsins are found in pearleyes (Scopelarchidae; Aulopiformes), and hatchetfishes (Sternoptychidae, Stomiiformes), and more than three rhodopsin genes are found in lanternfishes (Myctophiformes), spinyfins (Diretmidae), and tube-eye (Stylephoriformes). Photos (from top to bottom): Threadfin dragonfish, Echiostoma barbatum (Stomiiformes; photo Zuzana Musilova); pearleye, Benthalbella sp. (Aulopiformes; photo Zuzana Konvičková); and silver spinyfin, Diretmus argenteus (Trachichthyiformes; photo Vít Kaufman). Based on data from Collin and Partridge (1996), De Busserolles et al. (2017), De Busserolles et al. (2020), Lupše et al. (2021) and Musilova, Cortesi, et al. (2
