AdvertisementIn 2000, scientists spotted a bioluminescent mollusk in the deep sea. It turned out to be a new species of sea slug that's perfectly adapted to the deep ocean. Researchers from the MBARI dubbed it Bathydevius caudactylus and recently published their findings in the peer-reviewed journal Deep Sea Research Part I.Bathydevius is unlike any sea slug the scientists had ever seen. At first, no one knew how to classify the strange sea slug. A sea slug in the midnight zoneA low-light camera system captured the bioluminescence display of the Bathydevius caudactylus sea slug.

Investigating Bathydevius and its adaptations could reveal more about the midnight zone, which is the largest habitat on Earth and accounts for 70% of all seawater on the planet. A study describing the new species published Tuesday in the journal Deep Sea Research Part I. “The deep water column is maybe the last place you’d expect to find a nudibranch,” Robison said. The midnight zone is cold and dark and very forbidding to us terrestrial creatures, yet it is filled with life, albeit life forms adapted to a very different set of challenges than we face. The sea slug is bioluminescent, leading it to look "starry" when threatened.

☆ Firefly fossil reveals a previously undiscovered species that flickered during the time of dinosaurs

And now scientists have confirmed a new one: Diverse firefly species lit up the night during the late Mesozoic. The discovery comes from a fossil of an ancient firefly species that was initially discovered in 2016, trapped in 99 million-year-old Burmese amber from northern Myanmar. The beetle is only the second firefly species from the Mesozoic to be identified. Because only one other Cretaceous firefly species has been identified, “this new species can be used to revisit the (July 2022 study) to better date the evolution of fireflies given the new evidence,” he added. Firefly diversityThere are more than 2,000 firefly species found today, according to the Natural History Museum in London.

☆ I spent 12 days seeking Costa Rica's highlights, from the Cloud Forest to the Nicoya Peninsula. I'd revisit 3 places in a heartbeat but one tourist trap I'll never fall into again.

Read previewMy partner and I decided to splurge on a vacation to Costa Rica for a milestone birthday celebration this year. Costa Rica boasts 5% of the world's biodiversity, with white sand beaches and lush jungles to explore — a huge draw for us as animal lovers. My partner captured drone footage of our rafting trip down the Rio Celeste in Costa Rica. We chose to take a night walk that included a coffee and chocolate tour. I suggest a dedicated night walk tour, which usually begin at dusk, for a chance to see sloths and other creatures, rather than a gimmicky coffee and chocolate tour offered by many locations.

☆ In Coral Fossils, Searching for the First Glow of Bioluminescence
▼ + stars: | 2024-04-23 | by ( Sam Jones | ) www.nytimes.com time to read: +1 min

Bioluminescence is used throughout the animal kingdom, particularly in marine environments, to lure prey, startle predators and even act as camouflage in the surrounding light. “We always say it’s light-limited in the deep sea, but there are a lot of organisms that produce their own light,” said Andrea Quattrini, a zoologist at the Smithsonian National Museum of Natural History in Washington. The dazzling glow of bioluminescence is common in Octocorallia, also known as octocorals, a class of over 3,000 Anthozoa species including sea fans, sea pens and soft corals. The prevalence of bioluminescence in these sessile animals makes a lot of sense, Dr. Quattrini said: “They settle somewhere and they’re there.”How long organisms have been able to emit light is at the center of recent research by Dr. Quattrini and colleagues. Their latest study, published Tuesday in the journal Proceedings of the Royal Society B, resets the timing for the emergence of bioluminescence back to about 540 million years ago, from the existing understanding that it appeared in small marine crustaceans 267 million years ago.

☆ Ocean exploration: The benefits and risks

Ocean secretsA bioluminescent jellyfish is shown in an image taken during exploration of the Marianas Trench Marine National Monument. NOAA Office of Ocean Exploration/APThe deep ocean is an alien landscape that scientists have only just begun to understand. So much remains to be explored because reaching the bottom of the ocean is an incredibly difficult task. But the ocean depths have much to offer, including lifesaving compounds and the secrets of how life on Earth evolved. The event is nearly 10 months away, but people are already anticipating the total solar eclipse that will pass over Mexico, the US and Canada on April 8, 2024.

What lies at the bottom of the oceanWhile what’s considered the deep ocean extends from 3,280 feet to 19,685 feet (1,000 meters to 6,000 meters) beneath the surface, deep-sea trenches can plunge to 36,000 feet (11,000 meters), according to the Woods Hole Oceanographic Institution in Massachusetts. Alessandro Mancini/Alamy Stock PhotoWhy mapping the ocean is so challengingFrom a strictly scientific perspective, touristic trips to the ocean floor do little to advance our understanding of the ocean’s mysteries. “We want to go to the highest, the lowest, the longest.”But only a “very small percentage of the deep ocean, and even the middle ocean, has been seen by human eyes — an infinitesimal amount. “However, 150 years of modern oceanography have led to better understanding of many aspects of the ocean such as the life it contains, its chemistry and its role in the Earth system.”Mapping the ocean “helps us to understand how the shape of the seafloor affects ocean currents, and where marine life occurs,” Rogers added. Researchers say the ocean and the life it contains could provide answers to some of medicine’s biggest challenges, such as antibiotic drug resistance.

☆ How one family turned a job loss into an opportunity to sail the world

The family decided to leave Hong Kong to return to the Netherlands, where her husband, Jeroen, is from, she said. So the couple sold their home in the Netherlands and bought a secondhand monohull boat to "live and travel the world." Lisa Terauchi-D'RozarioThe family first sailed to France, then to Spain and Portugal, before reaching Sardinia, she said. While living at sea, her family used a water maker to turn seawater into drinking water, she said. The family checked weather forecasts often but, Lisa said, they still encountered situations they were not prepared for.
