Catfish are my favorite bony fish group by a wide margin. They range from parasites to apex predators, super venomous to electric, marine to fresh water. They suffocate dolphins, kill manatees, and send people to the hospital when stepped on or mishandled. Awesome group of fish!!

Panaque schaeferi is the largest of the armoured catfishes (Loricariidae), a wood eating species from large muddy rivers in the Western Amazon. The long bristles on the face and fins are modified teeth called odontodes. Photo by Nathan Lujan.

First author paper is out, ft. some pretty uCT scans I've been sitting on! Excited to see this one through with our team. Where do "odontodes" come from? What are they made of? How do they develop and regenerate in #sharks? #teeth #denticles #odontodes #evodevo

[Nathan K. Lujan @DrNathanLujan]

Also, loricariids are notable for having not only soft tentacles on the snout but also, in select taxa, some very impressive clusters of enlarged snout odontodes!

New fish day! Our new Ancistrus (armored catfish) have arrived. Excited for some new evodevo discoveries with @SultanofSauce! 🐱🐟 #evodevo #catfishtuesday #devbio #ancistrus

@LameaceH You might’ve just been dethroned as my favorite hungry unibrowed orb

[Nathan K. Lujan @DrNathanLujan]

Happy to have another opportunity to share this great specimen of #Acanthicus_hystrix....another reason why natural history collections are so important!

[Justin (정환) @justin_an74]

very intriguing find published this #FossilFriday: the new loricariid catfish Afrocascudo saharaensis from the Kem Kem!
found from the Oum Tkout locality, which has produced unique taxa such as Serenoichthys, it pushes back its family’s fossil record by over 35 ma

Find yourself someone who looks at you the way @SultanofSauce looks at this catfish

A great news piece from @ScienceMagazine featuring our new hammerhead #shark development paper @DevelopmentalDy
- Watch the hammerhead get its hammer | Science | AAAS 🔨🦈🔥 @UF_CLAS @UFBiology @FloridaMuseum https://t.co/R9PaBMjaTP

[Wesley Dillard @SultanofSauce]

@LSpucki @FDsignifier Was gonna put this exact one in the thread

[Gareth Fraser @garethjfraser]

Celebrating the end of semester with a Friday morning Fraser Lab breakfast! @Karly_Cohen is heading west in search of ghost sharks; Graydon is off to greener pastures after 2 years in the lab; and we welcome Gianna as our summer @NSF #REU student working on #shark skin teeth! 🦈

🚨‼️Its FINALLY out!! I am so excited to share my latest work on how cranial neural crest use post-transcriptional regulation to expand chromatin accessibility for the capacity to differentiate into multiple lineages🧵 @BCMFromtheLabs @CAGTHouston https://t.co/DFdhUFZ3nV

[Wesley Dillard @SultanofSauce]

@dgermanuci @garethjfraser @SICB_ @UFBiology @UF_CLAS @SICB_DEDB The scutes themselves are bony plates, but they’re covered in odontodes made of dentine and enamel!

[Ella Nicklin @Ella_Nicklin]

Unsure what talks to watch on the last day of #SICB2023? Like Sharks or Skates? Come see my talk on denticle development at 10.15 am in room 203-204!!! @SICB_DEDB @SICB_DCB_DVM

[Gareth Fraser @garethjfraser]

What a superb tooth-tastic talk by @Karly_Cohen #SICB2023 on the bizarre development of head-teeth (not denticles) in Chimaeras (Hydrolagus colliei; Spotted Ratfish)! Why not put a club-shaped, toothed 'jaw' on your forehead?! 🦷🦈🦷

[Wesley Dillard @SultanofSauce]

I had a great first @SICB talk on the evolution of odontodes in armored catfish. If you’re interested and didn’t catch it in person, be sure to catch it on SICB+!

[Gareth Fraser @garethjfraser]

Another amazing first, a fin-tastic first @SICB_ talk by @SultanofSauce (Wesley Dillard), who presented the developmental origins of the bone-embedded odontodes (skin teeth) on the surface of armored catfish (Ancistrus). New teeth or re-evolved ancient scales?? 🦷🥳 #SICB2023
