🚨 Fossilized Black Corals 🚨 Includes two transitional species too! Come learn about the evolutionary trend toward regularity in the axial skeleton from the Ordovician to modern day antipatharians (includes reduced ridges and a longitudinal fusion of networks). www.nature.com/articles/s42...

Unveiling the early evolution of black corals - Communications Biology

The authors describe two transitional species of Sterictopathes from the Middle Ordovician of Shaanxi, China, bridging the fossil gaps and thereby elevating the genus Sterictopathes to a new family, S...

#CrabAZ never ignores memes. M is for Macrocheira. This is both the largest arthropod alive (3.8 m or 12 ft leg span, only males are this extreme) and the only living species in its family. Mainly found in Japanese waters up to 600 m depth. (Yes we know it's Thursday, sorry) 🦀🧪🦑

Meme of Japanese spider crab. It's a red crab with cartoonishly long claws on a black background.

Congrats to Dr. Andrea Quattrini (Coral Curator, SI NMNH) for winning The Presidential Early Career Award for Scientists and Engineers! This is the highest honor bestowed by the United States federal government on outstanding scientists in the early stages of their independent research careers!

We use scanning electron microscopes to image skeletal features, which are used to identify or describe new species. This image shows branches of 𝘈𝘱𝘩𝘢𝘯𝘪𝘱𝘢𝘵𝘩𝘦𝘴 𝘱𝘶𝘦𝘳𝘵𝘰𝘳𝘪𝘤𝘰𝘦𝘯𝘴𝘪𝘴 (left) with a highlighted section showing the branch skeleton (middle) and skeletal spines (right). 🦑🧪🌊🐙

Left: Branches of Aphanipathes puertoricoensis Horowitz & Quattrini, 2023, a branch with some subbranches and a scale showing 5 cm, with a white box over a branch indicating the section shown in the middle image. Middle: Skeleton of the branch section that has rows of skeletal spines, with a white box highlighting the area shown in the right image. Right: Close-up of skeletal spines that have little bumps or tubercles, small surface features on the spines used to identify black coral species.

“Sunlight only penetrates up to 200 metres in crystal clear waters, and much less in murkier conditions. Beyond this depth, the world as terrestrial creatures know it ceases to exist, and life develops in total darkness. Welcome to the deep sea, the world’s largest ecosystem.”

The #DeepSea is the largest, darkest & least explored place on Earth. We’ve only scratched the surface–200,000 species down, millions more to go. But to discover these species, we must protect the deep sea from human impacts & activities. #DefendTheDeep www.downtoearth.org.in/wildlife-bio...
