A bubble coral shrimp (Hamopontonia physogrya).
This species is very small, typically less than 1 cm long. It is often found in bubble corals. The shrimp helps clean the corals of parasites and debris, while being provided with shelter in return.

Which is why I say "Trans rights are women's rights". Without those rights we all suffer.
We have been tracking people’s experiences with gendered spaces and our new report looks at the impact of the 2025 EHRC interim update on access to, and experiences within, gendered spaces in the UK.
![Image shows a row of toilet stalls with blue doors. Text reads: " I went to use the women's toilets as I was on my period and there were no gender neutral ones. A middle aged male security guard ran in after me…he started banging on the [cubicle] door, trying to open it as he shouted "sir, sir you can't be in here”... hearing the pitch of my voice was enough for him to drop it and leave. But I sat in the toilet feeling scared, vulnerable and dirty for a good few minutes." -a non-binary person tinyurl.com/ReportALoo](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:2dxbxnaywyhxdhuiiafrmy34/bafkreidejcnvaog3bhbxzgwcjjezztytalgxswj5nglv66zovq63le7oba@jpeg)

This study is WILD - some dinosaurs (reptiles) had hooves, and this is now the earliest known fossil of a hooved animal. Even crazier, mammals may have secondarily LOST their hooves through evolutionary adaptations (the origin of hooves is still kinda murky) www.science.org/doi/10.1126/...

Here in the UK, a friend of mine is having a hysterectomy at a private hospital. It will cost ~£7,000, including the hospital stay. What's wrong with the US health system that a broken ankle costs $64k?!
Our health care system is so broken it’s insane.

When you have an administration that so constantly, shamelessly, openly lies, pretty soon there’s no faith in any information streams coming from the administration, so there’s no way to convey true information in a way that lands right, which leads to more chaos.

Disinformation is dangerous because there’s no adequate way to retract it once it’s out there. It’s deliberately designed to cultivate powerful emotions (outrage, disgust, resentment, anxiety, etc) and those emotions don’t just disappear even when a person is told their feelings are based on lies.

The one-sided quest for bipartisan unity results in a constant moving of the goalposts rightward. That is the consistent lesson of the last 20 years of American history. A mistake that we seem condemned to repeat.
