Come. Sit with me. The world is wearing you down and you look in need of something wondrous.

Let us consider another reality unfolding right here on Earth, parallel to yours, miles below the sea: let us enter the dark and sparking world of the glitter worm... [a thread] Image Glitter worms, aka sparkling scale worms, were discovered a meager four years ago in two places: on the slopes of active deep-sea volcanoes, and around the bodies of decaying dead whales...

Image Ok, so I'm on this beach a long while ago in California. I'm walking looking for animals. Along the way, I'm picking up plastic. So I'm picking up all these random plastic shards and eventually I'm like ????? [📸 davems ] bit.ly/3exm95Q

OMG it literally took someone SWIMMING FROM HAWAII TO CALIFORNIA to discover this, but wow did we find something shocking in the Great Pacific Garbage Patch... [a thread 🧵]…
New study: plos.io/3LXY3CC It started when this guy name Ben Lecomte started swimming. He'd already freestyle'd his way from Japan to Hawaii, and now he was going to California. SWIMMING. And luckily for us… benlecomte.com Image

What's wrong with...

High-seas plastic cleanup
Deep-sea mining
Mesopelagic fishing
High-seas geoengineering?

In our new paper, we discovered a HUGE issue at the heart of these industries. And ignoring it is a risk to all of us... [a thread 🧵]
Study: bit.ly/3p4ZgyP ImageImage @DivaAmon @ashadevos @4kgjerde @HighSeasPolicy @DrCraigMc In 2019 my colleagues and I met in Liverpool to ask a simple question: for otherworldly ecosystems, like those on the high seas, where we know almost nothing, can we estimate the risks of human activities? It seemed so simple...

THIS IS SO COOL!
Scientists discovered that comb jellies, like this one, don't have brains with individual nerve cells. Instead, their nervous system wraps around their body & is made of ONE GIANT FUSED CELL! ...🧵
Study: science.org/doi/10.1126/sc…
📽️: bit.ly/3MVZVMZ Comb jellies come in so many shapes and sizes, but what they all have in common is being VERY STRANGE animals. When the animal tree first started growing, comb jellies branched off before anyone else, which means they're as different as a creature can be & still be an animal.... Image

THIS IS NOT A FISH!

This is an open ocean sea slug called Phylliroe. Phyliroe swims like a fish, hunts like a fish, and eats like a fish. This is an example of "convergent evolution," when animals do similar things nature selects similar body types.
...To be more precise, the sea slug Phylliroe is a type of sea slug known as a nudibranch, and is about the size and shape of a goldfish...

A heartfelt note from a Japanese scientist at the end of WWII, asking the arriving Allied Forces at Tokyo's marine station to spare the science lab form destruction. A US captain alerted the Naval base in Woods Hole, and the marine lab was spared.
@MBLScience @WHOI The note was written by Dr. Katsuma Dan, who had studied in many of the marine labs mentioned. The text reads: This is a marine biological station with her history of over sixty years. If you are from the East Coast, some of you might know Woods Hole or Mt. Desert or Tortugas...

Tonight I am thinking about Moon. A humpback whose back was broke by a ship strike. Who swam 4000 miles using only her pectoral fins. Who now resides in the waters around Hawaii, where she will likely die.
More info: theguardian.com/environment/20… Image The thing about science that I love and hate is that it never lets you rest. You want to believe in the savagery of nature but it won't let you rest there because then you see the beauty. And so you take shelter in the beauty only to meet the brutality again...

Having joined the blogging community at the beginning of the End Times, I'm not worried about a massive Twitter crash. I think this could be the start of the slow fade. People will drift away, join other platforms, form new circles in new spaces. It won't die. It'll be MySpace'd. Look at this fossil nerdyness. Once upon a time this article was shared far and wide, in places like Boing Boing and Huff Post. The Doggo Economy was rolling strong and the Noms of food love were upon us. The click-bait gold rush was real...

This strange blue animal gives me so much hope. If this improbable creature can survive on this planet, anything is possible [a thread 🧵]... Meet the waterproof ocean jelly Velella velella, a living sailboat far offshore. Above the waves its skin forms a living waterproof sail. Below the waves blue tentacles pulse and sway to catch food.

First up! Look at these baby golden jellies trying so hard! They've gotta swim fast because they're filter feeders, and fast swimming = happy eating!

WHY IS NO ONE TALKING ABOUT THIS?! The Ocean Voyages Institute has removed >200 tons of plastic from the Great Pacific Garbage Patch! ~1/500 of the estimated plastic! Sailors attach trackers to plastic & ships pick it up. Scalable, cheap, eco-friendly!
abc7news.com/ocean-voyages-… Image Large plastic in the ocean can concentrate into hot spots, like dust bunnies under a bed. Follow the plastic to hot spots, and pick it up without catching life in nets. It's kind of brilliant.

The risks of using giant nets to clean up plastic aside…

This will cost ~ 1 million dollars EVERY DAY to operate. Each system requires 2 ocean going vessels. That’s 20 vessels. Each ship this size, based on the time I’ve worked on them, costs $50k PER DAY…

Y’all— all the jellyfish biologists and coral biologists and sea anemone biologists are at a conference right now and it’s called CNIDOFEST because jelly/coral/anemone string cells are called “cnido” cytes and it’s so nerdy and I love these people so much 😭 Also there is honest to god so much dancing. No one dances like these people. I’ve been to EDC and literally had more fun at cnidofest and EDC was amazing so…
