I have also tried an alternate ā€žmore correctā€œ version with the medial antenna further towards the snout and the eyes a bit more to the back but it doesn’t look as cute

If life hands you a deadline, draw polychaete stickers!

(Am supposed to be working on velvet worm nephridia, but oh well…)

P.S.: This is true at least for Peripatopsidae. I think itā€˜s the same in Peripatidae too, but Iā€˜m not sure

P.P.S.: Drawings of the three nephridia in comparison coming soon! :D

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 ā€žtypicalā€œ 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??

Die letzten Wochen war hier alles gefroren. Einzig ein Entwässerungsgraben war eisfrei, aber in dem gibt es nur Ruderfußkrebse. Darum habe ich ausführlich Copepoden fotografiert. Von dorsal und ventral

Harpacticoida Copepoden sind nicht leicht zu fotografieren. Ich habe nur sehr wenige Fotos von denen. Heute habe ich ein Weibchen ventral mit angehƤngter Spermatophore ablichten kƶnnen.

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 Iā€˜m ordering a helicoid extension tube.

If youā€˜re in/around Bonn, definitely worth a visit! The exhibition is only around for a few days longer! (Until 06.04.)

A small part of the entire artwork. Crocheted corals of various kinds and other reef-life in yellows oranges and reds. It doesn’t even begin to capture the beauty of it irl

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 Iā€˜ve seen. Itā€˜s a collaboration by a few hundred (>1000?) artists.

Phyllodoce mucosa Phyllodoce mucosa from Isle of Man on March 30, 2025 at 04:10 PM by rhias

oh interesting! A polychaete Phyllodoce mucosa surrounding this green ball! is that where the species epithet comes from ? A mucus ball? eggs? interesting! #wormwednesday www.inaturalist.org/observations...

That’s probably eggs, I think. But they look like that in a lot of Phyllodoce species.
They also produce *tons* of defensive slime when they feel threatened. P. mucosa more than the others. Iā€˜ve handled one once for photography and the amount of slime these little guys produce is unbelievable.

View from underneath cherry tree in full pink bloom.
Due to the over-exposure the sky is almost completely white.

Reference pic of a small spring og beech leaves that are in the process off turning into their autumn outfit, changing from green through yellow and orange to brown. It's for the drawing in the next pic.

A colour pencil drawing of the turning beech leaves from the photo in the previous image. It's a reasonable representation of them.

Three copepods under UV from my sample last week. A female Pseudodiaptomus marinus, a female Pseudocalanus sp., and a Harpacticoida (I don’t know genus).

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

A helluva chonk of a bristle worm! This is the larva of a polychaete from the genus Scolelepis and it was hard to miss!

Closeup of A. branchialis against a black background. It is very clearly segmented. Every 5 segments is a chaetiger (bristle-carrying segment). Later (on from chaetiger 11 or 12) the worm has very pronounced branchiae that were definitely not a nightmare ar all to draw the black background around, I promise you. :)

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.

But omg. I’m gonna be SO good at colouring stuff when I’m finished with my thesis… You won’t even believe it!

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