Why do seahorses, goatfishes, dragonets and flying gurnards evolve differently across oceans? 🌏🐟 A new study led by Scripps researchers reveals that colonization dynamics drive the decoupling of species richness and morphological diversity. Dive in: https://t.co/tmdSSiK65w

Congrats to @Liz_C_Miller for leading this amazing work on deep-sea anglerfishes! 🌊✨ With 1,092 loci & CT scans, we revealed their adaptation from benthic to pelagic habitats—rapid diversification, bigger jaws, smaller eyes, & diverse body shapes. ⬇️ https://t.co/XPfwzLQMNe

1/📢 Exciting News! Using newly sequenced sea catfish genomes, we analyze signatures of selection across three major ecological axes within this clade. Our findings identify a heightened incidence of positive selection in marine-derived freshwater lineages. 🌊➡️🐟 #genomics

How did #flatfish develop the ultimate side-eye? 👀 Scripps marine biologist @R_BetancurR shares his research on flounder evolution with @carlzimmer of @nytimes, which sheds new light on how these flatfish adapted to sea-floor life over millions of years.

Flatfish offer an evolutionary puzzle: How did one eye gradually migrate to the other side?

1/ 🐟 Exciting discoveries in flatfish evolution! A study led by our former student Emanuell Ribeiro challenges the previous notion of convergent evolution in flatfishes and instead find support for a simpler, single-origin view https://t.co/hrxzIfR54h

We'll conduct fieldwork in New Guinea and collaborate with Australian and PNG researchers, including M. Hammer, P. Unmack, M. McGee, and A. Ko’ou. We'll also be recruiting undergraduate and graduate students and postdocs. Stay tuned for updates! #NSFfunded #fishes

Exciting news! Devin Bloom (@bloomchovies) and I have received an NSF grant to study the factors that promoted or constrained lineage, phenotypic, and genomic evolution of marine-derived freshwater fish radiations in tropical rivers in Australia and New Guinea.

Biological collections are repositories of the biodiversity on our planet, but they require critical infrastructure. We’re very thankful to @NSF @OUArtsSciences and @OU_Biology for supporting and recognizing the importance of collections 1/2
Phase two complete! Our ichthyology collection hasn't been this empty since 1999-2000! Next steps, install new railing for mobile shelving and storage. A big thanks to everyone in our herpetology collection and all other staff members who helped make this possible!

The Ichthyology collection at the museum has been hard at work developing a new app about all the fishes of Oklahoma! The beta version is set to launch in the coming weeks, so keep your eye out for it on the Apple and Android stores. #fish #fishesofoklahoma #comingsoon
