Pan-#Arctic distribution modeling reveals #ClimateChange driven poleward shifts of major gelatinous #zooplankton species https://aslopubs.onlinelibrary.wiley.com/doi/full/10.1002/lno.12568

"jellyfish and other gelatinous zooplankton could be some of the few organism groups to benefit from #climate change... the transparent #cnidarians, #ctenophores and pelagic #tunicates thrive on rising water temperatures, nutrient contamination and #overfishing."

"The ocean’s surface harbors an #ecosystem of colorful, understudied life, ranging from #protists and #cnidarians to #insects."

Oh I love this so much. Only #scientists will properly investigate the #biodiversity of #emojis ❤️

tl;dr: Vertebrates are significantly overrepresented. Arthropods, plants, fungi, and microorganisms are underrepresented. Diversity improved since the recent addition of #cnidarians and #annelids...

New genomes, old tricks! 🧬

Christine E. Schnitzler & team sequenced the H. symbiolongicarpus and H. echinata genomes revealing that their i-cells (pluripotent adult stem cells) are enriched in genes widely shared amongst animals. They also created the first single cell atlas for H. symbiolongicarpus. #preprint

An article published in the journal "Proceedings of the Royal Society B." reports the identification of the oldest known jellyfish species, dating back to about 508 million years ago, in the Cambrian period. A team of researchers named it Burgessomedusa phasmiformis after examining 182 exceptionally well-preserved specimens that were found in the famous Burgess Shale in Canada.

The 31 new deorphanized #neuropeptide #GPCRs from #Nematostella and the #phylogenetic trees also allowed us to predict the ligand for many receptors across #cnidarians. We hope that cnidarian researchers will functionally characterising these e.g. by #CRISPR, as the Houliston lab has done for the MIH receptor.

New animal family tree raises questions about the origin of nervous systems
Sponges are more closely related to us than some animals with a nervous system.
And that's before you get to the really weird stuff, like the radially symmetric Cnidarians, or the sponges that lack muscle and nerve cells. Or the comb jellies, which move themselves around by spinning lots of thread-like cilia. Or the truly bizarre placozoans, disk-like creatures that have two sides but no interior.

An article published in the journal "Proceedings of the Royal Society B: Biological Sciences" reports a study on specimens in an exceptional state of conservation of Gangtoucunia aspera, a primitive animal that lived during the Cambrian period, just over 500 million years ago.
