Ink sketch of some of the fish that can be let through with the Vishdeurbel. Shown are Bleak, Eel, Common roach, Perch, White bream, and Pike-perch.

Since it’s back tomorrow, #SundayFishSketch this week is some of the fish you can answer the Vishdeurbel for 🛎️🛎️ they all look very polite

This project is amazing by the way:

Damn, first acanthomorphs in the Early Cretaceous now „chromide revival“, I just updated my cichlid origins article last year….

Graphical abstract shows phylogeny of Pholidichthys

The origin of cichlids: The controversial phylogenomics of the convict fish, Pholidichthys leucotaenia

Very interesting. Will have to read in more detail later.
"... previous claims of a close evolutionary relationship between Pholidichthys and cichlids, while possible, are premature and warrant re-evaluation..."

Helsinki just went a full year without a single traffic death The capital city is Finnish’ed with car-related fatalities.

“Helsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”

the humiliation of going on a hot date then finding out she wasn't even in the same PHYLUM (then someone writes a whole paper about it, with photos of your wiener)

Paramblypterus, early Permian ganoid fish

Watercolor painting of a Green Chromis, Chromis viridis. Schools of these shy damsel fish hide in acropora coral in the Indo-Pacific. The similar Caribbean fish is the Blue Chromis. This post is part of a bigger project. I’ll be painting reef fish for the next 100 days 🐠 Colors, behaviors, weirdness, and wonder included.

A chain of salps, which are mostly translucent except for the organ at the bottom (I don't know what that is). There are two orange octopuses with white tentacles on the left and lower middle of the picture. There's a blurred thing which is probably a crustacean of some kind in the middle, and a small fish to the right of that. All of the passengers are either on or inside the salps - it's hard to tell which since they're almost completely transparent. #UnderwaterPhotography #Macro #Photography #MacroPhotography #Wildlife #WildlifePhotography

Salps serve as shelter for many other critters. This is part of a much longer chain of salps; there's two octopuses, a juvenile fish and what I think is an amphipod in this photo from a blackwater dive in Balayan Bay, Anilao

Many do, the P. sauvagei aren‘t the problem in this tank, but their tankmates are West African tilapias that are herbivores, it’s mostly Cryptocoryne that survive..

The Dream of the Butterfly

This is your regularly scheduled reminder to please take two seconds to check if that inflammatory post you’re about to share is factually accurate before sharing it. This is extra important in times of heightened stress and conflict, not less important.

In honor of Hans Dieter Sues a #FossilFriday, the big Kayentatherium that Hans built much of his dissertation around. Got to help excavate in July 1981 working for Farrish Jenkins and first met Hans, while he was working on the specimen at Harvard a few years later. @paleontologizing.bsky.social

Close up of a handwritten label on a fossil specimen: 'This Fossil is the first I ever obtained. It was purchased from Mary Anning in July 1824. It then wanted the point of the nose. This was found 3 years after rolled on the sands & she sent it to me to Oxford – Enniskillen'

#FossilFriday: A curator's dream label. Doesn't get much better than this: 'This Fossil is the first I ever obtained. It was purchased from Mary Anning in July 1824. It then wanted the point of the nose. This was found 3 years after rolled on the sands & she sent it to me to Oxford – Enniskillen'

Last week, amidst the hoopla over a new Speen, @fishfetisher.bsky.social suggested a review of naming papers in fancy journals in response to a post by @daveyfwright.bsky.social - I got bored after work and now I have (some) data!

Major Chinese funder to stop paying fees for 30 pricey open-access journals Move comes amid effort to grow the country’s own journals

Chinese Academy of Sciences plans on stopping using public funds to cover APC of expensive journals and caps publishing in them. To stimulate publications in considerably cheaper national papers.

Based. Lead by example. Defeat the system by rejecting it.

An extremely cool fossil of a bird head. Its eye and feathering are preserved as dark carbon traces.

Hive mind: Does anyone know if this Fur Formation bird fossil (MGUH 28.929) has been identified? All it's referred to as online and in papers is "bird head", which is not helpful.

A little yellow and brown frog in the groove in the middle of a vibrant green Pandanus frond, its feet splayed to the side to brace it in place.

Platypelis tuberifera always remind me of a rockclimber bridging a chimney, the way they sit in the groove of Pandanus fronds. Such charming frogs! And we know so very little about their ecology. For instance, as far as I know nobody has ever found their eggs or tadpoles! 🧪🐸🇲🇬

The British Museum photo shows a six-sided, cube-shaped die carved from rock crystal on a grey surface. The six sides are numbered one to six. The numbers are represented by circular incised markings, which comprise of a dark outer ring with a dark dot at the centre. Length: 9 - 13 millimetres, width: 9 - 13 millimetres. Display lighting casts a shadow beneath the die.

Timeless design!

Roman rock crystal gaming die marked one to six like modern dice 🎲 1st-2nd century AD.
