Did someone say resting fish face? The #LonghornCowfish is easy to spot with its bright yellow color and the signature horns jutting from its head. But those horns aren’t just for style — scientists think they evolved to make this little cowfish a mouthful most predators can’t swallow.

A three panel comic. In panel 1, two people are facing each other. The first person asks "Hey, do you want to drive really far and spend hours staring at distant, rapidly moving gray-brown objects while trying to find subtle differences between them?" and the second says "No." In panel 2, the first person says "What if they're bird-shaped?" and the second person says "Then absolutely, yes." In panel 3, the two people are standing and looking through binoculars at distant shorebirds on a beach. The first person says "Yay shorebirds season!" and the second says "Woo!"

Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts 🏝️... Turns out that 2/3 of these assertions are very wrong... 🌐 🦑🧪 🧵⬇️

When thinking of the 'model' planktivore on reefs, fusiliers come to mind - their fusiform bodies, forked caudal fins, and large eyes appear built for the job. But are these traits common among most plankton-feeding reef fishes? 🐟 🔗 The story is more nuanced than we thought: doi.org/10.1007/s111...

What do dolphins, toadfishes, and snapping shrimp have in common? They all go quiet when disaster strikes. We show that historic rainfalls in South Texas silenced an otherwise noisy estuary for several months, suggesting a sustained loss of ecosystem functioning. 👉 link.springer.com/article/10.1...
