Coral reef conservation is under pressure to act boldly in the face of climate-altered futures.

But how do we choose sustainable, responsible options?
Here, myself, @proftiffanym.bsky.social & David Bellwood introduce "MIMO". 👇

Our paper on Nautilus sex determination made the cover of @currentbiology.bsky.social !
With @reef-combo.bsky.social @anariesgo.bsky.social and Hector Torrado!

Check it out now!
Our latest issue is out!👇

On the cover: Nautilus ≈ 🐙+🐚

(Maybe — like the Nautilus — our journal is a living fossil, believing in the interest and inspiration our readers might draw from the diversity of biological systems, questions and approaches we try to feature🙏 )

New species alert! A Pascua goby from the Coral Sea. This genus now contains four species. Two from the Eastern Pacific and two from Australia, with more than 5,500km separating them. Lots of fun describing my second new species. #TeamFish #Fish

Naso! Great genus of surgeonfishes, sporting the vicious cutting scalpel blades at the base of their tail. Here is a better color photo of that bignose where you can see the tail blades.

Acanthuriform fishes! Research goals on Moorea are focused on morphology and evolution of defensive spines and backbones of surgeonfishes, angelfishes, and butterflyfishes. We have a scientific permit to collect specimens, and here are 2 beauties, Acanthurus lineatus and Pygoplites diacanthus. 🐟🦑🧪

Devonian ray-finned fishes were not particularly species rich, particularly compared to their lobe-finned cousins. This implies early actinopts might've also been anatomically monotonous. But a deep dive into their jaw anatomy w/ µCT reveals subtle but important structural diversity.
Curious about Devonian actinopterygian lower jaws? Look no further--our new paper provides comprehensive descriptions for 19 species in a tidy ~50 page summary! anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Out today in @plosbiology.org! We show that two major advances in fish feeding - highly protrusible jaws and large teeth - are functionally and evolutionarily incompatible with each other. @mikemihalitsis.bsky.social and Peter Wainwright. Free to read: journals.plos.org/plosbiology/...
Incompatibility between two major innovations shaped the diversification of fish feeding mechanisms
Large teeth and highly protrusible jaws are two feeding innovations that have evolved in fishes. High-speed videography and comparative phylogenetic analyses indicate that they are incompatible with e...

High-speed video shows that some reef fish can move their jaws side to side, a rare trait among vertebrates that enables efficient feeding on algae growing on rocks and in crevices. doi.org/g9hg4h
How are they biting? High-speed video reveals unexpected jaw movements in reef fish
Some reef fish have the unexpected ability to move their jaws from side to side, biologists at the University of California, Davis have discovered.

1/10 *** New paper out *** (on behalf of Nick Peoples who is not on Bluesky). I am beyond excited to present our new paper out now in @Nature! Here, we show that rapid gain and loss of tooth complexity accelerates diversification in fishes! www.nature.com/articles/s41...
Evolutionary lability of a key innovation spurs rapid diversification - Nature
A study shows that the rapid diversification of cichlids in African lakes is driven by their ability to evolve between having simple or complex teeth.

Congratulations to PhD student Nick Peoples in the Wainwright Lab on his first paper, looking at a key innovation across ray-finned fishes and its evolutionary dynamics. 🐟
