The @romtoronto.bsky.social Sharks exhibition is opening this weekend! The perfect family-friendly destination for the Thanksgiving long weekend!

I'm excited to be traveling to Lima, Peru, tomorrow to give a keynote lecture on "New approaches to the study of neotropical fishes: Genomics, eDNA, and computed tomography" at the National Life Sciences Congress.

Kicking off the 2025 ROM Population Genomics Symposium is @asherdcutter.bsky.social sharing new insights into the diversity of Caenorhabditis in the @romtoronto.bsky.social Glass Room.

Finally having the first lab meeting of 2025, with presentations on Acestrorhamphidae alpha taxonomy from Tiago Faria and 3D shape variation in loricariid opercles from Mikhail Clare!

Check out the gear on this Hemipsilichthys papillatus (MCP 39539), a member of the 'primitive' loricariid subfamily Delturinae from the Paraíba do Sul drainage in southeastern Brazil. It has large cheek odontodes like the more diverse Hypostominae subfamily, but it can't evert them.

I have some awesome students! Check out this velvet Pseudancistrus Anika made for…you can’t see it but the mouth is made of velcro bristles! And the watercolor!

Huh, looks like Chaetostoma loborhynchos Tschudi 1846, the type species of Chaetostoma, to me. Of course, who's to say whether this is a species that's been known for over 175 years, or one that's entirely new to science?

Through the e-COL+ project at @mnhn.fr I recently obtained data for this cranial CT-animation of #Vandellia_wieneri, an Ecuadorian #bloodfeeding_catfish that was described 115 years ago from the #Napo_River, is known only from this holotype, and is distinguished in part by its lack of dentary teeth.

Happy Thanksgiving!

….many more.
