Is it time for a bsky introduction? Hello I’m Rachel Hale, a Marine Biologist based in Aotearoa NZ. I study benthic ecosystems. I am interested in small animals that live on the seafloor, what they do, & how the diversity & behaviour of these ecosystems is affected by stresses like climate change

For this #molluscmonday and #marinelifemonday we got a Club-gilled nudibranch (Amphorina pallida). It was not exactly warm in the water on this day, a toasty 3 C. 🦑🤿 Taken: 2023-03-19 in Lysekil.

Stromatolites are fossil evidence of some of the earliest forms of life on earth, and some can be up to 3.45 billion years old! Stromatolites are formed when blankets of photosynthetic single-celled micro-organisms "cement" surrounding sediment in slowly growing layers.

Occidental Petroleum will begin operating the world’s largest carbon removal facility, Stratos, at the end of 2026. The facility is designed to remove up to 500,000 tonnes of CO₂ from the atmosphere annually. If it works, that's a time machine that will take us back by ~6 minutes every year.

Children: as problems in schools to be controlled; financial benefits to the state, but also burdens that must therefore be incentivised, for parents to have them; not in need of decent nutrition but still to be shamed for their bodies; & oh btw the Children’s Commissioner is sacked. FFS #nzpol

Earth systems don’t care about your borders. We solve the climate crisis as a planetary species or we don’t solve it. #NomadCentury

Have you noticed an opaqueness to the blue sky this morning? Wildfire smoke from North America is drifting south across the UK, meaning the clear skies may not be as blue as you might expect 🌤️

I've written a post about Echinomermella matsi, a roundworm which parasitises sea urchins. This worm can castrate or even reduce the lifespan of sea urchins, and this is a story about how these worms turned parasitic over the course of their evolution 🧪 dailyparasite.blogspot.com/2026/07/echi...

Interesting piece @science.org It's true that in the way scientific hierarchy is designed it generally rewards confirmation & penalises difference. What this paper misses is the epistemic injustice in recognition based on the identity of who presents the surprises. www.science.org/doi/10.1126/...

For #MolluscMonday, a grim one. The new IUCN Red List assessed every mollusc known to live only at hydrothermal vents. Of 201 species, 125 are now threatened with extinction, and the driver is deep-sea mining that has not meaningfully started yet. #marinelife iucn.org/press-releas...

Nephtyidae for Nephtys. (it should have been spelled Nephthys after the goddess, but someone stuffed up). Horrid spelling to get right.

Some delightful green Nereis (?) from San Francisco Bay taken a few years ago when I was visiting colleagues! #wormwednesday #worldpolychaeteDay

So can we, like, do something now? The time to start radical decarbonisation was years ago. Now we're on damage control and we STILL need to start radical decarbonisation. Vote!

France recorded a high of 44.6°C today. That’s so far beyond anything seen in the historical record, a 4.2 sigma deviation from the norm that it gives a return period of 87 thousand years. It’s really difficult to convey just how utterly extreme this is.
