DNA Reveals Giant Squid From Around the World are Remarkably Similar
“An analysis of tissue samples from 43 giant squid (Architeuthis spp.) from around the world… mostly from dead squid that had been found washed up on beaches or floating on the ocean surface, although a few came from animals that were accidentally caught by deep-sea trawlers… (revealed) the mitochondrial DNA of the creatures, irrespective of where they came from — be it be it California, Japan, South Africa, New Zealand or somewhere else — … (to be) genetically very similar.” …(read more)
I will be illustrating a giant pacific octopus (Enteroctopus dofleini) for the Monterey Bay Aquarium. I am wondering about the siphon--is this a paired organ, or do they have only one? I will be drawing the right side of the animal.
The “privileged state of subjective awareness in fact goes well beyond Homo sapiens, according to the new Cambridge Declaration on Consciousness (pdf), which was signed last month by a group of cognitive neuroscientists, computational neuroscientists, neuroanatomists, neuropharmacologists, neurophysiologists who attended the Francis Crick Memorial Conference on Consciousness in Human and non-Human Animals at Cambridge University in the U.K….” (click here to read more)
Just how giant are a giant squid’s eyes? It’s a question that’s vexed scientists for a long time, given that giant squids are rarely found while still alive. Then researchers tracked down a picture of a dying giant squid taken in 1981. In the photo, there’s a fuel hose crossing the eye’s pupil. The researchers used the size of this standard hose to calculate the eye’s dimensions. The whole unblinking eye was about 10.5 inches across; the pupil was about 3.5 inches across. -@acarvin
In this TED talk, the late underwater filmmaker and Biologist Mike deGruy (who was tragically killed in a helicopter crash in Australia around a week ago) talks about the importance of conserving the deep sea and his inspiration in the octopus.
