Always happy to be of assistance!
Would you be upset to know that the jaws are also poisonous? :P

I slowed down this vid in the beginning, but let it get to its actual real speed - crazy!
Admittedly, I kept wondering how this #polychaete #worm would be in a marinara sauce, covered in pecorino romano🤤
Shot in #Okinawa.

Also, my friend Tom turned the background black on this one and has also somehow managed to fix a huge stacking error I made. I have no idea how he did it, but it turned out amazing! :D

I'm still weirded out by how large the proboscis in Glycera spp. is. You can see the two darker spots in the top right coil of this worm (Glycera fallax). Those are the jaws. The proboscis goes all the way to there.

Sickening indeed. I still hope that some sweet day all these horrible people will be held accountable. >:(

I’m shooting a few mollusc photos for the profs at my university. This one (Calliostoma zizyphinum) is my favourite so far! :D

It’s a nice change not having to mind all the bristles and paddles of the polychaetes I usually deal with!

#marinelife #photography #mollusc #snail #invertebrates

Photos of Calliostoma zizyphinum from four different sides. The shell is cone shaped, roughly as tall as wide and has a beautiful red and white pattern.

On the bottom right there is a scale bar and the scientific name (in grey).

No marine organism today, but a photo I’m very proud of nonetheless.
It even got awarded “best photo” at the Botanical Garden Bioblitz earlier this year. :D

It’s a portrait of Bembecia ichneumoniformes, a wasp mimicking butterfly.

#macro #macrophotography #nature #insect #butterfly #entomology

The image shows the head and part of the thorax. It is covered in bright yellow and dark brown scales. In the middle you can see one large complex eye and a smaller, singular eye above. The antennae are brownish. Only the lower half is on the photo.

Thank you! :)
Yeah, they definitely remind me of dragons too! (See the post pinned to my profile :P)

Polychaetes are beautiful creatures and the Phyllodocid polychaetes especially have made me really fall love these animals ^^

I've not been very active recently, but I'm back for this #WormWednesday with a polychaete from my favourite Genus: Phyllodoce. :D

I think, this is P. mucosa.

#polychaete #worm #macrophotography #nature #naturephotography #marinelife

Closeup of P. mucosa on a black background. The worm is yellowish with brown spots and has a turquoise underside. It has transparent paddles on each segment and 6 long tentacular cirri on its head as well as four little antennae.

Here's the #InverteFest art book August 2025 cover posted in full - how many species can you identify in this piece? I'll post the answer later when I have the time to annotate the image.

A vertically long white drawing on black. the main figure is a wave of white, flowing from the bottom to the top composed of various invertebrates swimming and flying in unison - a sea slug, a bristle worm, a remipede, mosquito, jellies, and so on. lighter on the background are rough sketches of geometric pattern complementing the fluidly moving animals.

I don't really know what to do right now, I'm just waiting for some loading bars to finish loading, and I apparently have to be at the computer for this because otherwise it stops...

So I thought I'd share another cool animal: Hersiliodes latericius, a very orange copepod! :)

#MarineLife #Macro

A photo of Hersiliodes latericius under a microscope. The background was black-ish originally, but has been manually turned completely black.
The copepod is translucent yellowish with bright orange streaks. (It looks like some inner organ is orange, but I don't really know.)

It carries two large egg-sacs, which are also bright orange. The antennae are rather short.

Look at all the unlawful shit Trump et al. have already done. Experts on totalitarianism and dictatorships are leaving the US. I urge you, do something *before* the US becomes one! Right now is still the best chance with Harvard and loads of other independent institutions on your side.

Hannes @federgeistchen.bsky.social · May 23

It's frustrating to see people so confident that the law will stop this new attack of Trump against Harvard.
US-government doesn't care about the law and after the international students get their heads shaven and sent in shackles to wherever, no amount of being in the right can fix the situation.

In the meantime one could develop a grocery store map-app for every store. Like Wikipedia, it would be user-curated and the chewy-decimal system would be its backbone. Once you tap on the item you want, the shelf on the map gets highlighted. You could also plan your shopping with an optimal route.

Ive just done a 3 day workshop teaching people to paint #leaves in #watercolour at Cambridge university botanical gardens, & thought I'd share this teaching aid.

Quick & basic...& under 3 mins long!

I haven't posted an animal in ages, but don't think I've run out! There's plenty more to come. This very fashionable blue and red amphipod for example!

I sadly don't know anything about it apart from that it is an amphipod.

#MarineLife #Macrophotography #Crustacean #Amphipod #Nature #Animal

A closeup of an amphipod against a background.
You can see its left side. As mentioned, it is blue with red markings on each tergite. The eye is red as well.

To make up for this, I made really good pancakes just now. Best I’ve ever made.
