Fun fact: despite the name similarity, I have nothing to do with Pohlsepia or Palaeocadmus pohli 😉

Mexico Introduces Bill To Ban Octopus Farming Due To High Mortality Rates And Cannibalism Mexico has introduced a new bill to ban octopus farming after the Sisal farm reported a mortality rate of over 50 percent over 12 years

Cheering on Mexico [and sorry for photo]-'If successful, the proposed legislation would prohibit farming of any cephalopod species'. We badly need US federal law of similar nature. Grateful to US guvs taking the lead at state level. #octopus #banoctopusfarming #cephalopods #plantbased #animalrights

Did you know that #cephalopods have been around in some form or another for over 500 million years. That means they were here before the dinosaurs!

Did you know that octopus blood is blue as opposed to red as it contains hemocyanin which is copper based. This is part of what allows them to survive in colder waters. #cephalopods

A Pentameroceras mirum fossill with view of the aperture, held by a hand and with a scale bar. The cross section is circular, about 1 cm, and has one long horizontal slit, which is connected to four more slits about 1/4 to the left. Left side is dorsal, right side ventral.

A Pentameroceras mirum fossill with view of the right lateral side, held by a hand and with a scale bar. The specimen is about 2 cm long, with the apex on the left missing, and the aperture contracted, so that the fossil is more or less drop shaped (except for the missing tip/apex)

Here one of my favorite fossil #cephalopods for #FossilFriday:

Pentameroceras mirum from the #Silurian of #Gotland! Those narrow slits of the shell were likely where arms or eyes would stick out!

For those of us who grew up with the #socialbrainhypothesis, and #DunbarsNumber: new research on #cephalopods suggests that larger brains do not necessarily imply a larger number of social connections.Even #Dunbar appears to acknowledge that his theory applies more to #mammals than to other species.
