Float like a glass squid. What might it feel like to reach a state where your body’s density perfectly matches your surroundings? Their buoyant bodies are filled w/ ammonium chloride, which is lighter than seawater & helps them conserve energy. 1,729 m -#ArgentinianDeepSeeps

Benthic ctenophores clinging to tunicates along submarine canyon wall ~1.75 miles deep, during #ArgentinianDeepSeeps. Platyctenida have colloblasts, or sticky cells that release a mucus-like glue when they unspool extra-long tentacles into the water column, fishing for next meal.

Sea squirts & squid! ROV pilots filmed these salps and spectacular squid during the #SouthSandwichIslands expedition with @oceancensus in early 2025. Salps, also known as sea squirts, are ubiquitous throughout the Ocean, and abundant in the Southern Ocean.

あけましておめでとうございます。
午年にちなんでバテイクラゲ。馬蹄に見えますか。ちなみに学名もHippopodius hippopus（hippo-馬の、-podius脚をした）で、うまうまです。

【岩に広がる、3000年の命】
チリ・アタカマ砂漠に生えるヤレータ。苔のように見えるが、正体は枝葉が極端に密集した高山植物。岩のように硬く、人が乗れるほど。そして寿命は3,000年以上。成長を急がないことが、最強の生存戦略なのかも。

In the Atacama Desert in Chile, there's 3,000-year-old, densely packed shrub called llareta. It looks like moss covering rocks, but it's actually a cluster of branches and leaves that is so hard you can stand on it.

Like a tiny heart beating in time, this deep-sea jellyfish — Periphylla — pulses through the Ocean’s midwater. ROV pilots filmed this luminescent beauty at 920m along Argentina’s continental shelf, off the coast of Buenos Aires #ArgentinianDeepSeeps

Good news from Antarctica: the 2025 ozone hole is the 5th smallest since 1992, breaking up nearly 3 weeks earlier than average. Scientists say it’s shrinking because ozone-depleting chemicals are declining, thanks to the Montreal Protocol—proof global action works. 🌍❄️

#WildlifeWednesday: During our NA174 expedition to explore the deep sea of the #MarshallIslands, our Corps of Exploration saw this #cuskeel! Spotted at over 2,700 meters deep, our ROV pilots and video engineers enjoyed working together to get this critter on camera.

I presume this is a type of Myctophidae lanternfish, but I’m not 100% sure.
TL ~2.5cm

Question: what is the most insane fossil in the world?
Answer: the Holm preparation of Eurypterus.
These are Wenlock (~430 Ma) sea scorpions etched out of limestone with nitric acid and mounted on slides in the late 19th century.
LOOK AT THIS SHIT!
