'Mesmerizing spider threads' by Dr Martin J. Ramirez, captures two exceptional silk threads of the Australian net-caster spider, Asianopis subrufa.

We're excited to announce the finalists of the #RSPPhotoComp 2025! 🎉 Starting with #microimaging and overall winner, 'Mesmerizing spider threads' by Dr Martin Ramirez, capturing two exceptional silk threads of the Australian net-caster spider (sample obtained by Dr Jonas Wolff @evoimec.bsky.social).

Things that can happen while filming Portia in the field: we had a (not so) little visitor wandering by with his chicks! Not sure who was more surprised… #cassowary #portia #daintree #storiesfromthefield

🚨 Uh-oh!!! A suuuper hot #PhD opportunity just dropped! My friend and collaborator Massimo De Agrò is looking for someone to explore jumping spider vision and neurophysiology! #psychophysics #jumpingspiders #greatPI - apply!!!! (Deadline December 17th) 🚨

Meet our Plenary Speaker Daniela Rößler

Fueled by curiosity and a deep love of natural history Daniela discovered a REM-like sleep state in spiders and uses integrative field, lab and comparative approaches to investigate the function, ecology, and evolution of sleep across the spider tree of life.

Our tropical lab for the next couple of weeks :) #australia #daintree #spiders

It’s experiment time! While doing things in the field always adds an extra layer of difficulty (and also frustration), it is very rewarding once it works! #mosquitos #rain #stillhappy

Back in the field and beyond excited! 🕷️🌞🌿! #Portiafimbriata

PNAS Science Sessions – Webs and Leaps: Hunting adaptations of spiders. Available on all podcast platforms, subscribe and listen now!

Spiders are precision hunters, not just creepy crawlies. 🕷️ This PNAS Science Sessions episode dives into cutting-edge research on spider webs that hear, silk-powered lifts, and REM sleep-like states in jumping spiders. Tune into this Halloween Special: https://ow.ly/W5NO50XhCZ7

Two awesome news for our #SLEEB-Lab @unibonn.bsky.social 1) we finally had a lab photoshoot and 2) I can now officially announce @roald-arboel.com is joining our team as a Postdoc starting in November!!! Sweet tracking stuff ahead. Welcome to the #spider #behavior fam, Mikkel!

Amazing talk by Daniela @roesslerdaniela.bsky.social on spider sleep and possible adaptive values of rem sleep stages. Never knew spiders have sleep phases that eerily look like dream states. Traumhaft!! I wonder how many other creatures feature this behavior... Or how many don't!

🕷️ 🚨 Are you at the #DZG in Berlin next week? @dzg2025berlin.bsky.social my PhD @nadjageiger.bsky.social and I are very excited to tell you the latest about our spider sleep 💤 work! Come check out our talks on Friday and ask all your questions! :) 🚨 🕷️

The Local Organizing Commitee welcomes behavioral ecologists from across the world and of all career stages to enjoy a five-day meeting rich in top-notch science and ample networking opportunities in Turin (Italy), 20-24 July 2026.

Finally taking spider 🕷️ sleep 💤 to the wild! Currently in QLD, Australia, filming Portia fimbriata sleep in the field-which disturbances are they facing and how does their wild sleep compare to lab sleep? Stay tuned! 🙃 ps- terrible place to work 🤭 @nadjageiger.bsky.social @mherberstein.bsky.social

PhD position open with Dr. Jutta Schneider and @mherberstein.bsky.social in Hamburg, on sub-social behavior in crab spiders 🕷️ It even includes field work in Australia! Application deadline is 15 July, more info at the link:

We are proud to have @maxcapelle.bsky.social's paper out on bioRxiv! He found that phototactic behavior in #zebrafish switches during #ontogeny🐟🔆 Through elegant behavioral dissections, he identifies the navigational strategies related to this transition. www.biorxiv.org/content/10.1... Thread 👇

Guess I’m just gonna leave this video here as my intro tweet :) 🕷️💤 In my group, we study spider sleep! :) m.youtube.com/watch?v=BTcc...
