An ancient genome duplication event drives the development and evolution of spinnerets in spiders A genome duplication event during the Silurian played a crucial role in the evolutionary emergence of spinnerets in spiders.

The strongest spiderweb on Earth is spun only by females

Bark spiders are some of nature’s best engineers. They spin webs that stretch across entire rivers in Madagascar; their silk is stronger than steel—and the toughest on Earth.

But only females craft the mightiest webs, according to a new study. https://scim.ag/4pmXX8B

'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).

New paper on bark spiders, who build the largest webs made out of the toughest silk. We show that their extremely tough silk, which is potentially metabolically costly, is limited to large females. Juveniles and males use inferior silk.

Congratulations!!!

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.

This Male Walckenaeria acuminata may be common but its a fantastic looking spider, since getting into Linys this Genus is so fasinating. And its great that the male and female of this species can be Identified with a hand Lens.

Record-breaking success: Study on spider megacolony is the most popular article published by Pensoft In less than a month, a paper in Subterranean Biology surpassed nearly 27,000 Pensoft studies in popularity.

🎉 BROKEN RECORD!

🕸️ The recent discovery of a 100,000- #spider “megacity” on the border between Greece and Albania, published in our #openaccess, peer-reviewed journal @subtbiol.pensoft.net, became the most popular article across our entire #scientific portfolio, outperforming ~27,000 articles! 👏
