This Thanksgiving, break the ice by telling your family and friends how baby octopuses sometimes ride on jellyfish like little hats...[a thread]

It all began in 1957 when a scientist was SLAPPED by a jellyfish-wielding octopus. He published his harrowing tale in the prestigious journal science, and this is where our octopus story begins ...

...Baby female blanket octopuses live in the open ocean and use jellyfish as a weapon. When they're grown, they develop a stunning cape over 6 feet long. Males are 10,000 times smaller than females and ride jellies their whole lives. BUT...

They're not the only ones to ride jellyfish. Many open ocean octopuses, including paper nautilus, ride jellyfish. These amazing octos make THEIR OWN SHELL by putting their arms on their head and sweating out a little hat! AND THEY KNOW HOW TO DRIVE...
Paper nautilus octopus use strong jets of water to direct the jellyfish where to go, like riding a horse! And when they need to go fast...

...baby jellyfish-riding octopus ride through the ocean steering their jellyfish at breakneck speed! Look at this duo go!

So if you're struggling with what to talk to your family about this holiday season, just remember: half our planet is open ocean, which means there may be BILLIONS of tiny octopuses riding on jellyfish right now! Happy tgiving! [end of thread]

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]
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...
Study: bit.ly/3dIP6sC
We know very little about them, but a few things are clear even from these dark depths. Despite their beauty, they are rapacious predators and vicious competitors. Many glitter worm bear the bite marks of fellow glitter worms crowding around a meal (white arrows)...
Wanna hear a story about an ocean animal that is WATERPROOF, sails, and why I tried to accidentally recycle a bunch of them???? [a thread 🧵]...
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
What is this stuff? So I look closer and the plastic has rings. All the shards are shaped the same even though their different sizes. Then I realize: this is not plastic. These are skeletons...

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
The mission was clear: to swim to and through the HEART of the Great Pacific Garbage Patch. To see what is ACTUALLY out there. One stroke at a time, for months. And while he swam…
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 🧵]

@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...

We focused on the most accessible high seas ecosystem, the surface, and the largest novel activity impacting it: The Ocean Cleanup. We gathered everything known and used mathematical models to fill in the gaps. We discovered...

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…

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....
This means that they don't do things the way most other animals do. Including, apparently, the way they think. Comb jellies can see and respond to the world, just like other animals, but they are apparently doing it using a never-seen-before 'fused' nervous system...
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...
... Phylliroe’s ancestors long ago left the sheltered seafloor, evolving into open ocean hunters out for blood, or, if we’re being scientifically accurate, out for jelly.
Yep, this fish-shaped nudibranch eat jellyfish, like this one...
