Every time I've eaten octopus I'm like "I feel bad eating such an intelligent animal" and I imagine in another universe there are octopuses sitting around eating humans saying the same thing

Help to Stop Octopus Farming

I have narrated a beautiful and powerful animation about #OctopusFarming with my #PlantBasedTreaty friends.

Inspired by #Greenpeace 's A Monster in My Kitchen, Plant Based Treaty's talented animator #HoshimiSakai shows us the frightening reality of the millions of #octopuses destined to suffer if the multinational corporation #Pescanova is granted a permit to build the world's first octopus #FactoryFarm.

Guide to Squid, Cuttlefish and Octopuses of Australasia by Mark Norman & Amanda Reid, 2020

The Australasian region is home to the greatest diversity of cephalopods — squid, cuttlefish, octopuses — in the world. Yet, we know very little about these fascinating marine animals. This book provides insights into the biology and behaviour of more than 60 species.

Punching #Octopuses Lead #Fish on Hunting Parties
Octopuses and fish are routinely seen working together on the #ocean floor,. When an #octopus found an interesting crevice in the #coral or rock, it would cover the crack with its body, trying to capture any prey inside. The octopus’s hunting was more efficient when it was traveling with fish partners: It checked out fewer crevices, but spent more time at each one, suggesting it was finding prey to slurp up

In the waters of the Red Sea, #fish and #octopuses are forming an unlikely alliance:
They’re joining forces to track down prey, establishing a hunting operation that’s potentially more effective than either creature working alone.

With the octopus leading the charge, fish scout for hidden prey and signal where to capture a smaller fish or mollusk.
But if freeloading fish are hovering around, looking to benefit from the hunt without contributing, the octopus punches them away, according to new research.

️“The octopus basically works as the decider of the group,” Eduardo Sampaio, a researcher at the Max Planck Institute of Animal Behavior and lead author of the study, tells Nature News’ Helena Kudiabor.
The study, published on Monday in Nature Ecology & Evolution, brought a new type of collective behavior to light. Octopuses, often thought of as solitary creatures, led a group of various species of fish and discerned which ones were and weren’t helping

"How ‘Secrets of the Octopus’ Shows the Beauty, Intelligence, and Alien Charm of Octopuses"

I've eaten #octopuses (octopi?) since I was a child but, as I grow older, I sometimes question what I'm killing. Life is hard enough without facing such deep questions.

#Farming octopuses for their #meat would be cruel & inhumane. They can plan ahead, identify & remember humans individually, and solve complex tasks; #octopuses have different sleep phases, one deep & one with increased bodily activity, i.e. they may dream: https://e360.yale.edu/features/octopus-intelligence-conservation

#Octopuses could lose eyesight and struggle to survive if ocean temperatures keep rising, study finds - https://www.theguardian.com/environment/2024/apr/10/octopus-eyesight-loss-ocean-temperatures-global-heating and #spain wants to torture them to death for profit... #ClimateCrisis

A company in #Spain has a plan to torture a million #octopuses per year – by raising them in crowded tanks and then killing them by putting them in icy water, which causes a slow, stressful death.

The company knows octopuses are highly intelligent and feel pleasure, pain, joy and fear, but this is their way of turning a huge #profit. Now they’re being slammed by #scientists and the #media – and if enough of us add to the pressure right now we can stop them.

Females octopuses have eight tentacles, while the males only have seven and one specialized appendage for mating called a hectocotylus.
