#Scientists May Have Found the Blueprint of the Human Body at the Bottom of the Ocean
We know that some animals are #bilaterian—meaning they display #bilateralsymmetry—while others are not, but nature is rarely so black-and-white.
A study found that the sea anemone, a member of the #Cnidarian phylum, uses bilaterian-like techniques to form its body.

The version of record of our #Nematostella #GPCR #neuropeptide paper has now been published

For #cnidarian #neuroscience there are lots of new deorphanised receptors described in the paper. We also identified orthologs across cnidarian species, including corals, #Exaiptasia etc. so the resource is not limited to Nematostella.

Are there roles of DNA-incorporated N6-#methyldeoxyadenosine in animals?
Febrimarsa, Uri Frank et al #UniOfGalway show that its recycling from #m6A-containing RNA in #cnidarian embryos can delay #zygotic genome activation

By phylogenetic reconstruction, Daniel Thiel and Luis Yanez could show that #cnidarian #neuropeptide receptors diversified independent from #GPCRs in bilateria. This parallel #evolution and expansion confirms that cnidarians do not represent the ancestral state in neuronal signalling (as implied by terms like 'pre-bilaterian') any more than bilaterians.

So excited to see a #cnidarian represented!!!!!!

I'll pull these two out from the previous CW, as I don't think either is in any way affronting. If you want to see the two equivalent animals (another #mollusc, and #cnidarian) see the previous post.
Here's an amended description:
The first image is the beautiful radial skeleton of the Blue Button, or Porpita porpita, a colony organism (when alive), made up of cooperating hydroids. It drifts in the surface waters, using its stinging tentacles to capture small copepods, but will also hunt crabs and fish.
Next is a mollusc, which preys on the former, amongst other things.
It’s the beautiful violet sea snail, Janthina janthina, a free-floating snail that uses a raft of bubbles to keep it on the sea’s surface where it preys on hydrozoa. (Unlike the first, this was taken back home with my D700, not the iPhone3GS).

#Corals' biological clocks can function even without the #algae that nourish them

Temporal gene expression patterns in the #coral #Euphyllia paradivisa reveal the complexity of biological clocks in the #cnidarian-algal #symbiosis https://www.science.org/doi/10.1126/sciadv.abo6467

E. paradivisa exhibits tolerance to #CoralBleaching and survives without algae during prolonged darkness... Its #BiologicalClock functions even at a depth of 65 meters underwater and in almost complete darkness.
