🐸 Xenopus laevis 💚 The frog that shaped modern developmental biology! ✨ Xenopus embryos have revealed how the body axis forms, cells choose their fate, and tissues self-organize during early development 📹 Video by Bioquest Sudio and Xenbase #ModelMonday #DevBio

💚🦴 Fluorescence Friday: Halloween edition! 🎃 This glowing mouse embryo skeleton is serving serious spooky vibes 👻 Who knew bone development could look this eerie and elegant? 💀 Image by @EstermannMartin #FluorescenceFriday #SpookyScience

🥈 Second Prize – DevBio Art Contest 🎨 Hyloscirtus lynchi tadpoles captured in watercolor! 🐸 A tribute to this critically endangered Andean frog, showcasing its natural colors, unique hindlimb sacs & delicate morphology. 🌿 Painting by Sebastian Plata #DevBio #ScienceArt

Ascidians (Ciona intestinalis)🪸Our distant chordate cousins! 🌊 Simple sea squirts that reveal how vertebrate body plans evolved 🧬 A key model for notochord formation, neural induction, and cell lineage mapping 📸 Video by MBL Embryology 2019 #ModelMonday #DevBio #EvoDevo

Meet the real rainbow fish 🌈🐟 Using Cre-mediated recombination, each zebrafish cell expresses a unique fluorescent color, creating a living rainbow of developmental history 🎨✨ Image by Bret Pearson #FluorescenceFriday #Zebrafish #DevBio

💭Transitioning to independence isn’t only a Latinx concern! One key takeaway from our workshop at ICDB in Puerto Rico: this is a shared challenge across the field. 🌎Proud of the diversity — celebrating Latinx representation, gender balance, and early career voices in Dev Bio!

🏆 First Prize – DevBio Art Contest 🖼️ “A Model Meeting” by Karla Akari Garcia Inspired by The Quaker Meeting, this watercolor honors animal research models, from mouse to axolotl, that have advanced developmental biology 🎨 A tribute to science’s often unsung heroes. #DevBioArt
