New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

Direct development of stem tetrapods across the fin-to-limb transition

Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient la...

Day 27 of #Coverbirds! We’re down to the last 5 coverbirds, so I thought I’d throw in one I made in 2023. It sparked an idea for my #birdathon that I’ve finally gotten around to doing. Shouldn’t there be a guide for duck ID based on butts? I think so (1/5) #birds

Have you ever thought of all what animals can do when predation is not a big issue? In this review 👉 doi.org/10.1016/bs.a... @maribelrm.bsky.social @juancarvajalcastro.bsky.social and I show how aposematism can be viewed as an “umbrella trait” influencing multiple aspects of its bearers' lives🔴🟡⚫

Cool paper from Jeckel et. Al explaining how some dart frogs are spicier than others… 😝 royalsocietypublishing.org/rspb/article...

So grateful for this invigorating collaboration and funding opportunity! I can’t wait to see what we learn in the coming years in this multifaceted, intercontinental, multi-bicho team 🐸🐜🐌 🇨🇷🇬🇧🇳🇱

I am over the moon that my HFSP proposal w/ @joriskoene.bsky.social @stynoski.bsky.social @socialtransfernet.bsky.social has been funded! If you've heard my wild ravings on #socialfluids, commonalities across them and where this could lead, you see where we're going ❤️ Thank you @hfspo.bsky.social!

Granados-Martinez et al. (2025) ran behavioral field experiments to test whether male Strawberry Poison Frogs (Oophaga pumilio) rely on vision for navigation in tropical forests and open areas. Read a summary of their results at AmphibiaWeb.org #AWNews

This is really cool, it's a display of all the bugs found on a single tree. #Invertebrate

So the ‘#ChicagoRatHole’… wasn’t made by a rat after all? Our 3rd most popular paper this year, this #BiologyLetters study compared the imprint to eight local rodent species and revealed a 98.67% likelihood that hole was in fact left by a squirrel: doi.org/10.1098/rsbl...

5/ Some wings have evolved strategies to help reduce damage resulting from collisions. For example, we learned a few years ago that wasp wings have a flexible joint that acts like a reversible crumple zone, allowing the wing tip to easily bend out of the way when it hits things...

In what may be one of Earth’s craziest forms of mimicry, researchers in 2023 reported a species of rove beetle that grows a termite puppet on its back to fool real termites into feeding it. Learn more on #NationalWildlifeDay: https://scim.ag/4mM2aS9

Hemos registrado por primera vez un CO2 en la atmósfera superior a 430ppm. La última vez que esto ocurrió de forma consistente fue hace 14 millones de años. Los primeros restos de Homo Sapiens tienen 300.000 años, los primeros del género Homo hace 2,4 Millones. Vivimos tiempos extraordinarios
