Normally I prefer my fish to have bones but it was my first time seeing live sea lamprey at the American Fisheries Society annual conference in Ohio. Amazing fish! #weirdfish

While I have mostly researched Loricariids, this is their sister family Astroblepidae (outgroups are useful to understand). They are maybe more similar to some other catfishes compared to Loricariids. This fish is Astroblepus mindoensis from the NHM. CT scanned at the Uni of Bristol.

Yesterday I had the privilage to talk about my research and introduce Loricariids as a great/fascinating model for understanding evolution (particularly their morophology) at the #fsbi2026 symposium in Southampton. I really enjoyed the event and learnt so much!

First time using Bluesky, so I thought I'd show off two of the fishes I have worked with in a research context to answer questions in evolution but also keep as an aquarist. Ancistrus ranunculus and Panaque armbrusteri (partially segmented).

Are you a sucker for catfish? You're in luck! Here, the evolutionary innovation of fused molariform pharyngeal jaws in suckermouth catfish is explored, helping to uncover whether these fancy mouths opened up new feeding opportunities in loricariid catfishes! 🧪 🌍 👇 doi.org/10.1093/evol...

A suckermouth catfish sits on the floor of what's likely a large tank, it's infamous mouth hovering over tiny rocks. It's skin is mottled with yellow and brown.
