Covering The Oceans In Darkness….

Behold the blue glaucus (Glaucus atlanticus), a tiny sea slug that packs a powerful punch! Growing only about 1.2 in (3 cm) long, it’s also known as the blue dragon, and it specializes in eating venomous siphonophores—like the Portuguese man o' war. It then repurposes the toxic chemicals from its prey as a defense for itself. The blue glaucus’ sting has been known to induce nausea, vomiting, and agonizing pain. Their venom can remain active even after death!

When wood turns into glitter

Many moons ago, in the area that is now Nevada ancient woodlands were living through events that would result in some stunning pieces that grace museums around the world. Some 14 million years ago in the Miocene, the area was thickly forested rather than displaying the arid environment of today. It was also much closer to sea level, since the area has been extensively uplifted since then, due to tectonic stresses caused by the subduction of the Pacific and Farallon plates under the North American one. The area also saw intense subduction related volcanism (ongoing along the USA’s west coast to this day), which periodically covered the forests in silica rich ash. As groundwater interacted with the magma below, weathering the layers of ash into clays, it dissolved silica, precipitating it when conditions such as temperature and pressure changed, replacing the ash covered trees with opal, sometimes so clearly that every cell is visible. While not really suitable for jewellery use due to its tendency to crack as it dries out (called crazing in the trade), these rare logs from the Virgin Valley of Nevada make for stunning collector’s specimens

“I make sure that when I am boating that nothing goes into the water, I try to recycle everything I can, and I don’t eat seafood unless it is invasive lionfish. I also participate in as many coastal cleanups to help to remove all of the garbage along our shorelines and I try to encourage others to do the same. We have a long ways to go in ocean conservation, but national marine sanctuaries, along with national parks, monuments, and wildlife refuges, afford us the best opportunity to help leverage limited resources to address coastal and marine conservation."

DISCOVERING THE GIANTS OF THE DEEP: BATHYNOMUS JAMESI

A newly discovered species of giant isopod, Bathynomus vaderi, has recently been described from the deep waters around Spratly Islands, off Vietnam. The species, named after the infamous Sith Lord, Darth Vader, due to the striking resemblance of its helmet-like head, adds to the growing diversity of the Bathynomus genus. Bathynomus vaderi is characterized by several unique features, including a parallel-margin clypeal region, a raised dorsal surface on its pleotelson, and upwardly curved pleotelson spines.

Giant isopods like Bathynomus vaderi have become an expensive delicacy in Vietnam. Until 2017, local fishermen only sold them as an incidental product at low prices, but in recent years the media has drawn the public's attention to this unusual seafood. Some even claim that it is more delicious than lobster, the "king of seafood." This new species is described from several individual found at seafood markets in Hanoi, Vietnam.

In Vietnam, Bathynomus species, are often referred to as "sea bugs". Their unique appearance and large size make them a delicacy, and they can command high prices, with larger individuals of B. vaderi reaching up to 2 kg. In recent years, demand for these creatures has risen, especially in urban centers like Hanoi and Hồ Chí Minh City, where they are displayed in restaurants and sold through online seafood markets. This growing industry highlights the continued fascination with deep-sea species and the need for ongoing research to better understand their ecology and conservation.
