Found three different species of pseudoscorpions yesterday and they‘re all from different species as well! :D #arthropod #mesofauna #pseudoscorpion #arachnid

I don’t remember whether I posted this one, but for this #WormWednesday here‘s Alentia gelatinosa! 🪱 #MarineLife #Polychaete

If life hands you a deadline, draw polychaete stickers! (Am supposed to be working on velvet worm nephridia, but oh well…) #polychaete #worm #art #marinelife

Onychophorans are weird. They have 3 different kinds of nephridia. Small ones in the first 3 pairs of legs. Huge ones in 4 and 5. And „typical“ ones in all the remaining ones. Also in 4 or 5, instead of having the opening (nephridiopore) at the base of the legs, they open right at the feet. Wth??

Breaking news! I have successfully adapted the camera to my microscope! Yaaay! Still need a bit more distance for parfocality with the eye pieces, so I‘m ordering a helicoid extension tube.

Went to a marine exhibition at the Bundeskunsthalle today. Great exhibition all the way through. But I was particularly stunned by the crocheted coral reef. I think this is one of the most beautiful and impressive works of art I‘ve seen. It‘s a collaboration by a few hundred (>1000?) artists.

Just a photo from yesterday‘s walk that‘s horribly overexposed, but that I like a lot. Spring is here! :D #cherryblossom #spring

I‘m gonna have a great day tomorrow! :D

Another copepod for you! <3 I just think they‘re very neat. This one‘s Eucyclops sp. #pondlife #microscopy #crustacean #copepod

Another Onychophore post! :) This time the whole animal from the side. I’m surprised by how well the colours got preserved. Apparently it has been collected a couple decades back and stored in ethanol ever since #onychophore #photography #macrophotography

Haven’t posted a polychaete in a while… :) This one’s Arenicolides branchialis. I love this very deep and dark iridescent green colour it has. In person it looked almost black. #polychaete #worm #WormWednesday

I hope, the people whom I’ve told “I’m doing 3D reconstruction of animals with a microCT scanner to visualise their anatomy and morphology” never find out that most of that is just me colouring in pictures like in a colouring book.

First proper microscopy session with the new scope! Experimenting with the light to get a DIC-like effect. This is what I got so far. I’m quite happy, but it only really works on the 20x objective! ^^ Images show stuff growing on a copepod. #microscopy

Yet again the same worm. Regular photo this time. I just finished turning the background black. :) The little “paws” are very cute, but the mouth is terrifying. #photography #macro #worm #onychophora

Same Onychophore (velvet worm) as yesterday, but from the outside. It looks so alien! :D #biology #worm #3D
