A juvenile of the beautiful Arctosa cinerea spiders which live on the river gravels in northern UK hill streams/rivers

weit weniger willkommen ...

aber zum glück entdeckt bevor sie sich richtig festsetzen konnte, war noch leicht herauszuziehen

leute gebt acht, da sind echt viele unterwegs, ich bin nur einmal abgezweigt um zu sehen ob es schon morcheln gibt und habe noch nicht einmal die gestrüppige ecke durchforstet

Migraine-induced insomnia tonight, so have some more pics of the spider organs 3d model. A few tweaks since last pics; had to adjust the positions of some organs to match up with the outside of the body.

Got the abdomen ready to print, so we'll see how it goes!

Abdomen is done, mostly. The rest of the "space" is mostly digestive glands (I think?), which I'll add once I see how this works printed/painted.

The weird tabs on the book lungs/spinnerets, are openings for me to put paint into the cavities. We'll see how it works!

First jumping spider of the season

For #FossilFriday, meet a weirdo. This is a phalangiotarbid arachnid. The animals are weird - lots of their segments are bunched up towards the middle on the top surface, but not on the bottom. High resolution CT doesn't reveal that much more than you see in the rock.

I think all the organs and such in the cephalothorax are done. Still working on the abdomen. (Spider internal organs 3d model. Hopefully will eventually be 3d printed.)

Spider people, how's it looking?

Spider organs 3d model WIP. The plan is to 3d print in clear resin, with the organs as cavities I can fill with colored paint. I don't know if this will work!

(Spider experts, feel free to offer advice. Be gentle, I'm learning spider biology as I go. This is a mygalomorph.)

Chelifer sp.
