#CombJellies reveal ancient origins of animal #genome regulation
Long-distance control of #genes appeared 650-700 million years ago, much earlier than previously thoughthttps://www.eurekalert.org/news-releases/1082644 #science #evolution #development

This is so cool, and makes me thing of Lynn Margulis claims that cell fusion, symbiosis are at the heart of speciation. #wildlife #evodevo #evolbiol #combjellies

"Researchers discovered that some comb jellies can fuse their bodies together when injured. The unique adaptation, which involves merging their nervous systems and stomachs, has never been seen in any other species."

Injured #ctenophores, uniquely, can #fuse together into a single organism, even integrating their #nervous and #gastric systems.
Scientists accidentally find deep-sea 'jelly' creatures merged into 'single entity' after injury, revealing bizarre new behavior | Live Science https://www.livescience.com/animals/scientists-accidentally-find-deep-sea-jelly-creatures-merged-into-single-entity-after-injury-revealing-bizarre-new-behavior #science #biology #MarineBiology #CombJellies

Physiological integration of fused #ctenophores https://www.cell.com/current-biology/abstract/S0960-9822(24)01023-6
"2 individuals readily turn into 1 following an injury. Afterwards, they rapidly synchronize their muscle contractions, merge digestive tracts to share food"

Homeocurvature adaptation of phospholipids to pressure in deep-sea invertebrates https://www.science.org/doi/10.1126/science.adm7607
"Cell membranes from #CombJellies reveal a new kind of adaptation to the #DeepSea: curvy lipids that conform to an ideal shape under pressure."

From #ctenophores to #scyphozoans: parasitic spillover of a burrowing sea anemone https://www.nature.com/articles/s41598-024-72168-7
"Some #SeaAnemones have developed a unique way to overcome the challenges of ocean dispersal. These anemones parasitize jelly-like marine #animals called #CombJellies to spread more easily through the #ocean... This study has uncovered the first documented cases of parasitic anemone planulae in true jellyfish"

"#Ctenophores have developed unique lipid structures to compensate for the intense pressure that are separate from the ones that compensate for intense cold... so much so that the pressure is actually what's holding their cell membranes together"

Antarctica’s fragile #plankton ready for research https://www.antarctica.gov.au/news/2024/antarcticas-fragile-jellies-ready-for-research/
"For the first time, a range of fragile and exotic #MarineCreatures, captured in waters off #Antarctica in perfect condition, are being housed in the Australian Antarctic Division’s research #aquarium. The gelatinous organisms include predatory #SeaAngels and #CombJellies that were captured in RSV #Nuyina’s unique ‘wet well’, during a recent voyage to Mawson research station."

🧠🐙 Some of the most primitive animals on Earth have neurons unlike any others. A new study suggests that neurons evolved more than once in the history of life, challenging the conventional view of brain evolution. #neurons #evolution #combjellies https://www.scientificamerican.com/article/did-neurons-evolve-twice/

What did the earliest animals look like?Chromosome analysis resolves debate about sister group of all animals. It's comb jellies, not sponges
https://www.eurekalert.org/news-releases/989327 I'm pretty sure I've seen a "definitive" answer to that question a few years ago. Don't recall who won that time.
