Two miles under the ocean, off the coast of Argentina, scientists stumbled on creatures that don’t look like they belong on Earth. They found pale pink lobsters, a squid so transparent you could see right through it with what looked like a horn sticking out of its head, and a crab with a hundred tiny barnacles riding on its shell. Some of these animals looked goofy, others creepy, but all of them were fascinating.
The expedition took place in July and August, when scientists aboard the Schmidt Ocean Institute’s research vessel “Falkor (too)” sent an underwater robot down into the Mar del Plata Canyon. That canyon, almost twice as deep as the Grand Canyon, cuts through the seabed just off Argentina’s coast. For three weeks, the robot recorded hours of video, and the scientists were stunned by what they saw. They spotted more than 40 species that no one may have ever seen before.
Daniel Lauretta, the chief scientist from the Argentine Museum of Natural Sciences, said one of the highlights was a massive patch of red corals that looked like a field of beets. He started calling it the “Beet Field,” and the name stuck. People following the expedition online had their own favorite moment: a goofy-looking sea star that looked exactly like Patrick from SpongeBob SquarePants. Watching these creatures in real time made the whole thing feel like a mix of science and nature documentary with a dash of cartoon humor.
Although the scientists had visited the canyon before, around a decade ago, they only had fishing nets and trawls to bring things up to the surface. It gave them a sense of the life down there, but it wasn’t the same. With today’s technology, such as high-resolution cameras and underwater robots that can roam freely, they could watch the animals alive in their natural setting.
The Mar del Plata Canyon itself plays a big role in why it’s so full of life. It sits about 190 miles off Argentina’s northeastern coast, right where two strong ocean currents meet. One is a warm, salty current flowing down from the tropics. The other is cold and nutrient-rich, traveling up from Antarctica. When they collide, they create one of the most energetic mixing zones in the ocean, creating a perfect recipe for biodiversity.
Jonathan Flores, a marine biologist with Argentina’s National Scientific and Technical Research Council, didn’t join the expedition, but he watched the livestreams and reviewed footage. He said deep-sea canyons like Mar del Plata are very important for biodiversity and may shelter creatures found nowhere else on Earth. The problem is, we’ve barely scratched the surface in studying them. Flores pointed out that exploration like this isn’t just about curiosity; it’s about documenting species before they disappear and understanding how these fragile ecosystems might respond to climate change or human activity.
The images from the canyon were breathtaking. A mother octopus curled around her eggs, keeping them safe. There were lobsters in shades of pink wandering in groups across the seafloor. Red crabs scurried among orange and peach-colored corals. A jellyfish with a glowing red body shimmered in the darkness like a tiny lantern. To human eyes, it looked like a pink dream world at the bottom of the ocean, but as scientists explained, those bright red hues aren’t for show. Down in the deep, red light disappears, so being red is actually the perfect camouflage, as it makes the animals nearly invisible in their dark environment.
Some of the animals were collected and brought back to labs to study. Confirming whether something is truly a new species takes time, sometimes as long as a few years. One common method is DNA barcoding, which means sequencing a small piece of mitochondrial DNA and comparing it to known species. But in many cases, especially in the deep sea, the database just doesn’t exist yet. Some organisms have never even had their DNA recorded before, which makes the process even slower. Mike Vecchione, a zoologist with the U.S. National Oceanic and Atmospheric Administration who wasn’t part of the expedition, said that’s just the reality of deep-sea biology. Cataloging these creatures takes patience, and sometimes decades of work.
Even with all the challenges, scientists weren’t surprised to find so many possible new species in such a short time. According to Flores, that’s what usually happens in deep-sea research. These ecosystems are still so poorly studied that every new expedition turns up animals we’ve never seen before.
For the scientists, this trip was about building a baseline. Getting a first real picture of what lives in the canyon and how the ecosystem works is crucial for conservation. Without knowing what’s there, it’s impossible to protect it from threats like deep-sea mining, trawling, or the broader impacts of climate change.
In the end, this expedition wasn’t just about finding funny-looking squid or colorful crabs. It was about realizing how much of Earth is still mysterious. Every dive reminds us that our planet is still full of surprises, and sometimes the strangest and most beautiful things are hidden in the places we almost never look.
