Farm-bred octopus: A benefit to the species or an act of cruelty?

If you have Netflix I highly recommend a move called My Octopus Teacher. Very well done film.

"My Octopus Teacher is a 2020 Netflix Original documentary film directed by Pippa Ehrlich and James Reed, which documents a year spent by filmmaker Craig Foster forging a relationship with a wild common octopus in a South African kelp forest. At the 93rd Academy Awards, it won the award for Best Documentary Feature."


I was a volunteer diver at Monterey Bay Aquarium a long time ago and they had a big octopus. Highly intelligent and was an escape artist. Kept getting out and was found numerous times crawling around on the floor. I believe the installation of astroturf around the top of the tank finally worked at containment.

Thanks for the tip.  I added the documentary to our watchlist.

Interestingly, octopus can extract up to 40% of the oxygen it needs through the skin.  They have 3 hearts, two for the gills and a third that keeps the blood moving whether or not the gills have access to water.  While not terrestrial creatures, sometimes they can and do purposely move over land very short distances (from tidepool to tidepool) because of their ability to extract oxygen in their unique way.  There are also species that are transparent, with only the brain, eyes, and optic nerves being opaque.
