Blind cave spiders~
This occurs due to the process of regressive evolution. In an environment without light, vision provides no advantage in finding prey or avoiding predators. The loss of their eyes means that energy and resources once used for eyes are instead allocated to other traits.
Appreciated :) it'll be weird to no longer roam the halls of Corson-Mudd at night...
Thanks man, if you're ever in the neighborhood, I'll have some spiders to show off! Hope to see you in Vancouver?
Thanks Peter :) hope all is well in your neck of the woods.

Light pollution is a major factor in insect population declines. Switching to narrow-band LED lighting and shaded outdoor lighting could make a major difference. 🧪

Hey All: Google is pulling the "automatically on for anyone over 18" bullshit with Gemini that the Dropbox did for its AI, but I can't afford to ditch Google Drive/Docs/Workspace.
If you have a personal Google Account, first go to gemini.google.com/extensions and turn everything off...
Man...do you ever wonder if like...WE are the weird ones??

We just re-locate our twitter/X-history with the help of @blueark.app and then our moving will be final. Please help us to build a new #neuroethology community here by asking colleagues to follow us and by using hashtags or linking @neuroethology.org so that we can share your content 🧪🧠🦋🪲🐝🦑🐟🦐🐜🐦🐸🐢🦈🪼

Olfaction in spiders. We found that the wall pore sensilla in spiders look similar from the outside to those of insects, but differ ultrastructurally in various ways. Independent evolution!

My first time being part of a published article! Everything about Dolomedes in one place. I wrote the section on parental care. 🕷️
I am very grateful to all of the collaborators on this paper especially Dr. Chrissie Painting and my advisor Eileen.

Alright arachnologists and arachnid enthusiasts, let’s get this started! Drop a comment below if you would like to be added or have people to add. Let’s make the official AAS starter pack 💪🕷️🦂🕸️
go.bsky.app/8Nb8974
I made a starter pack for animal behaviour researchers / ethologists! please share and feel free to self-nominate or suggest others to be added as this is very much still a work in progress and not an exhaustive list 🌍🧪😊 #SciSky #BioSky #AnimalBehaviour #AnimalBehavior #Ethology

Hi! Could you please add me if there's still room in pack 2?
Digitally altered image of a snow flake made out of spider legs and silk.
Unaltered photograph of Net-casting spider stretching its net.
Okedoke, giving this app another shot. Really miss the art and science I used to see on Twitter.
Here's a quick contribution: Net-casting spider + radial symmetry = seasonally appropriate image from upstate NY.
Posting the original image too because I think it's also pretty cool :)
Hi! I'm a senior undergrad entomology major at Cornell in the Hoy lab working with @jaystafstrom.bsky.social on the downward-facing eyes of ogre-faced spiders! Interested in sensory biology & behavior - especially with arthropod study systems (spiders haha). Looking forward to meeting new people :)
Unfortunately no, she was just chillin. Was also at night though, so she was probably a bit surprised when I rolled up with my headlamp that shines with the light of a thousand suns.
same vibes:
Oh boy, you were in for a treat then. There are some super cool studies that show Portia is probably the smartest spider around (or at least tested so far). The fact they can stalk prey, go on a little detour, and get back to it is just...yea, mind blowing for a spider.
Thanks a bunch! Definitely more floofy than I was expecting, too.
Friday the 13th in #Arachtober...gotta share something worthy of the occasion. Here's the first Portia I ever saw :) She was a delight.
It is an easy way to find my people, though
Are folks doing #Arachtober over here?
