Coming soon! 😅

Fish deformities are commonly observed in farmed or non-native species. Here, we report for the first time a pughead deformity in a wild specimen of Satanoperca jurupari from the Tocantins River, within the Amazon basin. 👉 www.alb.periodikos.com.br/article/doi/...

We have collected this discus fish that seems to present some head deformity. Can anyone agree with me about it?

Someone spotted me! #fish

Between 2019 and 2023, researchers paid $8.968 billion to make papers open access. Imagine what else could be done with this money if it wasnt paid to for profit publishing companies... 👉 arxiv.org/abs/2407.16551

I'm happy to share my research published on Biota Neotropica. Rapids in the Tocantins-Araguaia Basin host a rich fish diversity adapted to strong currents. Despite hydroelectric impacts, these habitats remain crucial for the survival of species. #Fish #Conservation scielo.br/j/bn/a/PJwBM... #Fish

This armored catfish seems to be a putative new species of Peckoltia. It resembles Peckoltia vittata but it misses the fully platted abdomen. What do you think?

Gonatodes tapajonicus, collected near São Luiz do Tapajós by my fellow herpetologists in a multidisciplinary field expedition that happened in October of 2023.

Mostrando que não há limites para o vira-latismo e que não pode ver uma vergonha na rua que já quer passar, @helderbarbalhoreal.bsky.social, o anfitrião da #COP30, saúda a posse do criminoso condenado que quer assassinar o Acordo de Paris. www.poder360.com.br/poder-susten...

Here is an intriguing specimen of Ghost Pleco (Ancistomus snethlageae) showing a dark band along the dorsal and caudal fins instead of the diagnostic white bands on the fins. Could you have a hypothesis for it?

Having a 3D fun time!

What amazing Baryancistrus aff niveatus we caught in the Trombetas rapids.

The Tocantins toadfish, Potamobatrachus trispinosus, is one of the rarest fish species in Brazil. Since its discovery by Collette in 1995 was only known from its type locality, which was tragically submerged by the Tucurui Hydroelectric Dam. #TeamFish, #FishSci, #Fish, #Ichthyology

Well this explains why Angel sharks are one of the most threatened shark species: genetics show very isolated populations despite neighbouring islands, with deep oceans likely acting as barriers to gene transfer. Means protecting just one population won't work link.springer.com/article/10.1...

My paper of the description of Hypancistrus parkateje was divulged in the Miami Herald. www.miamiherald.com/news/nation-... #fish, #fishnews

Mouth details of Leporacanthicus joselimai, a threatened species of Brazilian freshwater. #TeamFish, #FishSci, #Fish, #Ichthyology

New paper alert: A time-calibrated phylogeny of Neotropical freshwater fishes, the most diverse continental fauna on Earth. Built from a supermatrix of 51 genomic markers for 3,167 species, the most species-rich phylogeny of this fauna to date. frontiersin.org/journals/bio...

My first species description was published last week in Journal of Fish Biology. We expanded Hypancistrus's distribution to the Tocantins watershed, presenting multilocus phylogeny and CT-scan images to support taxonomic positioning. Find out more at: doi.org/10.1111/jfb....

There are any fish researchers up here?
