Same! This is a genuine PSA. I bought into the stigma against fish and thought they were boring. It’s perhaps the thing I’ve been most wrong about.

They have so many beautiful patterns and colors! So many weird ways to arrange bones! So many superpowers!

Fish cranial kinesis model is now listed in my Etsy shop! Hopefully useful for showing the mechanism that opens and closes a teleost fish's mouth.

Not if it’s resting on my ponytail. And if it does start to exert an uncomfortable pressure, it can easily be moved around and adjusted.

A woman with her hair in a ponytail wearing a face mask. The face mask ear loops are not looped around her ears, they’re hooked onto a piece of wire that is hidden in her hair. It’s basically a headband of wire that ends in small hooks just above and in front of her ears.

The wire contraption. It is a thin piece of aluminum wire that is shaped like the top of a head, but with a small bump at the top, to hook around the ponytail for stability. The two ends of the wires are hooks.

I’ve noticed a lot of the discomfort comes from ear loops, so I recommend the ones that loop around the head. If those don’t work for you, you can copy my weird contraption.

The lizard depicted here is likely Bachia flavescens!

Having more reduced hind limbs than forelimbs is extremely rare among limb reduced lizards, but happens most often in the group Gymnophthalmidae.

A long lizard with a tiny arm and an even tinier back leg. It is scooting along on a tile with its tongue sticking out.

A long lizard with a tiny arm and an even tinier back leg. It is scooting along on a tile with its tongue sticking out.

Three fingers on each hand and one toe on each foot is extremely rare. I’ve only heard of it occurring in some specimens of Bachia flavescens, who usually have just a thigh and shin going on, with no feet!

I appreciate all the people showing love and support to me. I’m so grateful honestly. It means a lot. The ban isn’t that big of a deal for me. I think it was wrong and the explanation was bullshit. But that’s ok and I accept. Social media comes and goes. I’m grateful for all the connections I was able to make and all the people I get to be connected with off Bluesky. More importantly, the world needs more people to give a fuck. More people to give a fuck about Palestinians, more people to give a fuck about disabled folks, more people to give a fuck about our queer and trans siblings, more people to give a fuck about Black liberation. The world, and Bluesky, is full of bootlickers who will do anything to avoid doing anything to upset the status quo. These people are cowards groveling to those in power in hopes of protection. I just hope people continue to show love and care and kindness. Mutual aid is so important. Give when you can, boost when you can. We only survive this together.

Purple background, white text, which says ... the fact that the stories in One Message Remains are written as a series of vignettes and not as a neat progression towards the fall of the Treotan Empire is a strength of the collection's writing. Each story follows a protagonist who, regardless of their initial orientation towards the Empire, is forced to reckon with the role in the regime.

@ericderoulet.bsky.social's new (free!) essay discusses living under imperial subjugation, and approaches to resistance, as depicted in @premeemohamed.com's One Message Remains collection ... timely perhaps?
