The Hawaiian creation myth relates that the present cosmos is only the last of a series, having arisen in stages from the wreck of the previous universe. In this account, the octopus is the lone survivor of the previous, alien universe.
Artist Satoshi Tomizu creates small glass spheres that appear to be miniature solar systems or galaxies, in which planets made of opal are circling into spirals of colored glass and gold flakes.
Each piece includes a small glass loop allowing them to be transformed into a beautiful pendant.
Contrary to most mollusks, octopuses have a closed circulatory system (i.e. blood is contained within vessels). To pump the flow,
Octopuses have three hearts: two branchial hearts and one systemic heart
The branchial hearts pump blood to the gills, where oxygen is taken up. Blood then flows to the systemic heart, where it is pumped to the rest of the body.
They are all located at the back of the mantle, so you will often see anatomy illustration with the legend “heart” instead of “hearts”.
Thanks to M.J. Wells studies, we also know that when an octopus is really excited or startled, its heart misses a beat or two. Fortunately, any single octopus heart can stop for some time, the remaining two providing enough circulation to keep the animal alive for a while (more on that, and love, in another post).
We got up close and personal with the octopus at the aquarium today! The kids learned a lot of stuff today and they got to explore with the creatures of the ocean. #sealife #sealifeaquarium #octopus #friend (at SEA LIFE Charlotte-Concord)
It’s clear that #GiantPacificOctopus is smart—smart enough even to outsmart their aquarists now and again. Webster recalls a time she was feeding Cordelia, an octopus whose name means “daughter of the sea,” while giving a behind-the-scenes tour. “I went down to grab another piece of food, and there wasn’t any left,” she says. “She had it in her arms. She had figured out where I kept her bin, and she had reached in, grabbed it and pulled it back out. They’re very smart, very intelligent creatures, so I had to learn to move the bin around.” 📝📸: @nationalaquarium

After one exhausting week and tons of feedback from paleonerds and graphic designers, the cladograms are finally here! These cladograms explain the relationships between notable genera within the group Sauria which encompasses all modern reptiles including birds.
