The bite of sicariid spiders such as the brown recluse can cause tissue necrosis. Crystal structures of the Chilean six-eyed sand spider’s venom toxin reveal how the toxin breaks apart cells—information that could help develop treatments. In PNAS: https://ow.ly/u5aw50YFJlR

Na 1ª Conferência #FAPESP 2026, “Por um #Museu Comprometido”, Aurélie Clemente-Ruiz, diretora do @museedelhomme.fr, sustentou que essas instituições culturais precisam ir além da conservação e assumir papel ativo nos debates contemporâneos. agencia.fapesp.br/57615

Exciting times ahead - I'm beyond delighted to be joining @bristolbiosci.bsky.social in 2026! 🎉🕷️🎉🐌🎉 I'm also looking for a PhD student to join @multipleye-lab.bsky.social in our new home! Come and study the effects of light pollution on the evolution and development of spider eyes with us 🌃🕷️👀 👇

My first pseudoscorpion observation was pure luck. Happen to see this wasp and took a shot. It was only later did I see what was hanging on the antenna. On iNaturalist [ www.inaturalist.org/observations... ]

#microCT scan of the left palpal bulb (male copulatory organ) of a grass spider I found wandering Beckman's hallways last week! 😍(He was on his last legs when he was preserved for the scan). Taken in the Microscopy Suite of @beckmanillinois.bsky.social and rendered in the Visualization Lab.

We love jumping spiders because they are smol, cute, active, friendly and always looking around curiously with their huge eyes. But do you know they’re also masters of mimicry? Check out the bugs they pretend to be (and some of those are really good)!💚💚

Using high-speed transnasal imaging, electroglottography, and acoustic analysis, this new #JRSocInterface paper studies ten distinct phonation types in a professional metal singer: royalsocietypublishing.org/doi/10.1098/... #biophysics

Our arachno-colleague, Dr. Peter Jaeger, has the ambitious goal of running an inclusive and low-budget scientific conference: the Asian Conference of Arachnology (ACA) 2025. All donations will cover travel and conference expenses for students and ECR from low-income regions in Asia. #arachnology

The curious morphology of the treehoppers can help them detect different electrical charges and even distinguish friend from foe. Excellent work! This is one of the coolest things I've ever read!

@cesarfavacho.bsky.social and I made a video to present the results of our recently published paper on Tapixaua callida (subtitles in PT and EN). This fascinating spider mimics ants in a way very similar to the Asian species Pranburia mahannopi, described by arachnologist Christa Deeleman-Reinhold.

🕷️🌍🕸️ Spiders aren't creepy crawlies—they're ecosystem heroes! From pest control to biotech inspiration to key figures in our collective culture, a new review reveals the many services spiders provide: 🔗 doi.org/10.1111/brv.... (drawing by @jmalumbresolarte.bsky.social)

I had a lot of fun giving this interview - I wish my research always had dramatic music in the background

Caterpillars can sense predators before contact – by detecting their electric fields! 🐛 Recent @pnas.org study led by @samjakeengland.bsky.social won the Cozzarelli Prize. Congrats, Sam – brilliant work on insect electroreception! 🎉 🔗 www.pnas.org/doi/abs/10.1... 📽️ www.youtube.com/watch?v=VTjX...

Wallace’s day at Museu Goeldi!

"What's the Point of Natural History Collections?" is out today on the YouTube/AntLab check it out and long live basic research!!!!!!!!!! youtu.be/dxUbTn7d6Fw

Happy #Invertefest! Celebrate invertebrate biodiversity 🐛💕

Thinking about arachnid paraphyly ⚒️🧪

cute

Arthropod decline, particularly in cities, has devastating consequences for predators. Consequently, globally invasive urban spiders are well adapted to long-term starvation (>42 weeks), as demonstrated in my first paper since my PhD. @cp-iscience.bsky.social doi.org/10.1016/j.isci.2024.110722

A comic about the good stuff

Our latest paper on the jump kinematics and choreography in the Oz Splendid Peacock spider. We filmed & analysed locomotory jumps in male & female spiders. The males are incredibly light - measuring just 2mg - and oh they can jump! Videos in the thread. Open Access - read here: tinyurl.com/4bnpz9tz

The lab is delighted to release the first genome for the giant American vinegaroon! The slowly-evolving order Uropygi captures the strongest signature yet of the arachnopulmonate whole genome duplication. #biodiversity #genomics academic.oup.com/jhered/advan...

In research evaluation quantitative data (publications, citations etc.) is often decisive. Yet, researchers contribute in many diverse ways. To seek more inclusive methods, we joined the Coalition for Advancing Research Assessment (CoARA). #AcademicSky www.humboldt-foundation.de/en/explore/n...

Always great to see the process :)

Sea spiders (Pycnogonida) are an ancient Class of chelicerates with a fascinating evolutionary tale. A new study we just published on the EJLS uncovers their evolutionary history! 🧵 #Evolution #TheLinneanSociety #SeaSpiders #Arthropoda academic.oup.com/evolinnean/a...

For #FossilFriday may I present to you an amazing scorpion, Pulmonoscorpius kirktonensis. It may look like the moult of a modern species, but these are actually ~330 million year old fossils, dissolved out of a rock from 🏴󠁧󠁢󠁳󠁣󠁴󠁿 using acid. ⚒️🧪🦀🦑 #evosky

Exciting #Arachnology news! It's been clear for some time that spiders have 'noses' on their legs but we didn't really understand how they smell airborne sex pheromones. Now we do! Gabriele Uhl & colleagues have identified the sensilla responsible: 🕷️🧪 www.uni-greifswald.de/en/universit...

Fantastic!

It is my pleasure to announce that Part I of the special issue on arachnids in the Boletim do Museu Paraense Emílio Goeldi - Ciências Naturais has been published! Available online at boletimcn.museu-goeldi.br/bcnaturais/i...

Con gente del MACN, CEPAVE y Uruguay, recién describimos la araña Pikelinia schiapelliae (Filistatidae), hallada en arenales de Argentina y Uruguay. Muy simpática! (foto 1 por Damián Hagopián)

#Education resource! Over the years I created this collection of colored skull #3Dmodels for teaching. They're available to download on MorphoSource & to view on Sketchfab. Because of recent changes to Sketchfab, I migrated them to my website: www.graysvertebrateanatomy.com/work/colorso... (1/3)
