I have a feeling that every legacy news org besides Fox will always be seen as the "liberal media" by the audience they're trying to appease now. That perception is entrenched and they won't grow viewers this way.

I guess the risk is converting naive viewers who are unaware of the regime change.

Just yesterday, the Trump admin banned the use of terms like 'climate change' and 'emissions' at the Department of Energy, even on internal documents. They are not even allowed to discuss it amongst themselves. Let the callous madness of that sink in.

Okinawa had its hottest September at 1.6C above the average. I filmed this mass coral bleaching last year, but didn't have the heart to share. Total annihilation of the first few meters of depth. This stuff happens before our eyes, and yet people who think it isn't real keep gaining power.

I'll have to admit, there's a self-own in the notion that "what the administration said they will do is insufficient evidence of what they will do", but it helps no one

Yajaagama cave: Turning back at the clearing and heading out.

Yajaagama cave: Human bones. The cave is a historical burial ground with many broken urns. The remains are placed in several places, like the clearing at the end. Apparently the locals are fine with leaving them be.

The exit of Yajaagama. You're supposed to turn around at this clearing, although the cave actually continues just beyond it. You can see that this clearing was once part of the cave that has collapsed.

Parts of the cave look like it's melting. The dark specs here are inse.. cts.A species or subspecies of cave cricket (クメカマドウマ). These are one of the most common things in the cave, although I couldn't find much information on them.

Yajaagama cave: Close to the exit, there were this endemic subspecies of ground gecko, Goniurosaurus kuroiwae yamashinae. Beautiful stripes.

Yajaagama cave: Parts of the cave have glittering minerals. Sometimes they form beautiful little terraced pools.

Yajaagama cave: In many places it looked like there were veins of gold or some such mineral, but up close they turn out to be growths of lichen, covered in little droplets of water so they glitter.

Yajaagama cave: The ceilings were the domain of the oogeji (Thereuopoda clunifera), a type of centipede. They are about 10cm long I think. Never seen ones this huge, or so many. It's not one of the endemic species however.

Yagaajima cave: This is a species of land-dwelling isopod endemic to Kume, with distinct yellow spots. It has a Japanese common name but is a scientifically undescribed species (Ligia sp.). Here in the cave it is 800m away from the closest seashore, where isopods of this genus are usually found.

Yajaagama, a cave on Kume Island. Supposed to be 800m long and closed off at various points, some areas for bat conservation, some because they are unsafe. Filled with endemic wildlife, darkness, and human bones.

The footage quality is poor, but this is a rare Rhina ancylostoma, bowmouth guitarfish, seen in Oura Bay (Okinawa), where they are building a new US marine corps base. It's a type of ray. I've never seen one in the wild before!

I was looking at the many orange sponges in area thinking 'it would be cool if one of these was a frogfish'. And one of them was.

Excited to share our study on sailing siphonophores, AKA bluebottles or man-o'-war! 🌊 we received hundreds of samples from scientists around the world, part of a huge effort to sequence genomes and test for multiple species 🧬 out today in @currentbiology.bsky.social doi.org/10.1016/j.cu... 🦑🧪📌

A sea elephant (heteropod) flapping its lazy way through the night. Something about the motion of its fin is weird and hypnotic.
