Evolution of the ray-finned fish brain Ray-finned fishes can be considered as the most successful group of vertebrates as they represent roughly half of the extant species diversity of vert…

I wanted this to be a text that can be used by those that want to start exploring brain anatomy and evolution in ray-finned fishes, which is something that I personally think was lacking in the literature.

I’m delighted to share my first ever book chapter is out now!
I goal with this piece is to provide a detailed but approachable review of ray-finned fish brain anatomy, anatomical diversity and evolutionary patterns.

It’s so much fun spending more than a decade working on my career, making sacrifices, achieving important milestones and contributing to science and society to then receive job rejections like this:

On the left, a narrow, glass-fronted display case with a mix of letterpress, hand-bound, antiquarian, and collectors' books; stretching off to the right, 8-foot bookcases laden with literary and contemporary commercial fiction, about one thousand books out of the 6-7 thousand in that section. LED lighting and light-colored wood cases and flooring keep the room feeling relatively spacious despite the sheer quantity of books.

Communities need used-book shops.

As the trends in our world are increasingly standardized and entrenched by "predictive" technologies that stifle innovation and reduce human actions into economic categories...

We need a full range of possibilities for readers and communities to explore and share.

Couldn’t agree more

27-28yo - publish these brains in fancy journals;

29yo - Finish PhD and start postdoc at Harvard

18yo - Start working at a paleo lab, looking at fossil sharks, including the ones my mom chose for my 1yo party;

21yo - my first 2 papers are published;

22yo - I describe my first new fossil species;

23yo - I find fossil fish brains!!

12yo - I learn to dive and spearfish and get together my fish anatomy basics;

12yo - I meet a paleontologist for the first time at a book release;

17yo - I finish high school and get into college for a bio degree;

(cont.)

1yo - my mom chose plastic fossil fish to decorate my first birthday party;

4yo - hitting a quartzite wall with a hammer it falls over me (but I love it);

5yo - I watch Jurassic Park;

6yo - I find my first fossils;

(continued)

BOLSONARO PRESO

I have it. Its a great source!

If you replace ‘bird’ with ‘fish’ its the question I ask myself everyday

The interplay of different structures of the vertebrate head is such a fascinating topic that I want to make my whole career be about it

I’m happy that sponges are back to their sacred place

NEW pub in @science.org 🥳

Is it sponges (panels A & B) or comb jellies (C & D) that root the animal tree of life?

For over 15 years, #phylogenomic studies have been divided.

We provide new evidence suggesting that...

It's irritating that they describe the effects of his racism as limited to causing controversy within science and reputational consequences for himself rather than giving an immeasurable boost, false veneer of legitimacy, and idiot-friendly prestige to modern scientific racism and eugenics.

Amia is great by itself though!

Hoje é um dia histórico. Demos um passo decisivo para um país mais justo, com um sistema tributário que torna a contribuição mais equilibrada e reconhece o esforço de todos que ajudam a construir o Brasil. (+)

@friedmanlab.bsky.social @rodrigoichthys.bsky.social @fishfetisher.bsky.social I’m finding your GARS at the University of Michigan Museum of Natural History! Hope you’ll share some for #GarWeek next week!

I'm telling my student the horrors of Brazilian academic job searches on Halloween and that seam fitting

Nanotyrannichthys is my suggestion if anyone is describing a small lizard fish (fossil or extant)

My first book chapter should be out soon and I’m really looking forward to sharing it with everyone!

New preprint led by the brilliant @aleksandra-marconi.bsky.social on cichlid brain diversification, fgf8a signalling and regulatory divergence with TEs on the mix! All part of a wonderful collaboration with @ebablab.bsky.social

Ha! finding convoluted ways to keep fish sitting straight up in the tomograph is a highlight of my best work days 😅
