In this issue, Chen et al. present the first population genomics analyses of Indian Ocean hydrothermal vent animals, using eight populations of the scaly-foot snail (Chrysomallon squamiferum) distributed across three mid-ocean ridges. They show an asymmetric south-to-north gene flow driven by deep currents and aided by ghost populations. Their results also identify source-sink dynamics and dispersal barriers essential for conservation planning in the context of upcoming deep-sea mining. The scaly-foot snail is an iconic vent-endemic species famed for the iron-infused sclerites on its foot and functions as a flagship species in deep-sea conservation efforts.

This curious worm uprooted itself from the sand like a carrot being pulled up by an invisible person, and rolled around in the current for a bit before starting to dig itself back in. You can see the sand grains slowly traveling over some mucous layer as it slowly reverses into the sand.
Even more excited โ our paper is featured on the cover of Science Advances!
Huge thanks to @alexandrejan.bsky.social who took this incredible photo of a ctenophore (aka comb jelly) and the editors.

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. :)
Havenโt posted a polychaete in a whileโฆ :)
This oneโs Arenicolides branchialis. I love this very deep and dark iridescent green colour it has. In person it looked almost black.

A colorful poster illustration featuring 15 species of animals from the Cambrian period 541-485 million years ago. These are mostly unusual looking invertebrates, such as Hurdia, Wiwaxia, Anomalocaris, Peytoia, trilobites, Marrella, Nectocaris, Hallucigenia, Opabinia, Plectronoceras, Lyrarapax, and Naraoia. An early chordate (Pikaia) is also included. The animals are brightly colored on a dark black background. White numbers with a key label each species.
Creatures of the Cambrian period!

What a dedicated dad!
The male tiger #jawfish holds the clutch of eggs in his mouth until the behbehies hatch, ~8-9 days later. I usually find them in small groups of 3-5 individuals, each in their own private burrow, spread over an area of ~6โ or so.

The news about students seeking compensation from universities for COVID teaching has made me quite sad.
I can't say what happened at those universities, or what those student's experience was. My present university did not appear to be in the list.
But what I can say is...
