Octopuses die after mating and laying eggs

“You’d chase them under the tank, back and forth, like you were chasing a cat,”

Octopuses in captivity actually escape their watery enclosures with alarming frequency.

Some, she said, “would lift their arms out of the water like dogs jump up to greet you.”

How do you prove the intelligence of someone so different?”

Small brain size was the evidence once used to argue that birds were stupid—before some birds were proven intelligent enough to compose music, invent dance steps, ask questions, and do math.

BIOLOGISTS HAVE LONG NOTED the similarities between the eyes of an octopus and the eyes of a human.

Three-fifths of an octopus’s neurons are not in the brain; they’re in its arms.

“It is as if each arm has a mind of its own,”

researchers who cut off an octopus’s arm (which the octopus can regrow) discovered that not only does the arm crawl away on its own, but if the arm meets a food item, it seizes it—and tries to pass it to where the mouth would be if the arm were still connected to its body. 

the skin of the cuttlefish Sepia officinalis, a color-changing cousin of octopuses, contains gene sequences usually expressed only in the light-sensing retina of the eye

In other words, cephalopods—octopuses, cuttlefish, and squid—may be able to see with their skin.

“Home,” Mather found, is where octopuses spend most of their time. A home, or den, which an octopus may occupy only a few days before switching to a new one, is a place where the shell-less octopus can safely hide: a hole in a rock, a discarded shell, or a cubbyhole in a sunken ship. One species, the Pacific red octopus, particularly likes to den in stubby, brown, glass beer bottles.

This octopus wasn’t the only one to use the bottle as a toy.

not only can these animals play with toys, but they may need to play with toys.

Octopuses have the largest brains of any invertebrate

“Octopuses,” writes philosopher Godfrey-Smith, “are a separate experiment in the evolution of the mind.”

the natural lifespan of a giant Pacific octopus is only three years

Except to mate, most octopuses have little to do with others of their kind.

we have to change the way we think of the nature of the mind itself to take into account minds with less of a centralized self.”

“I think consciousness comes in different flavors,” agrees Mather. “Some may have consciousness in a way we may not be able to imagine.”

This time I offered her only one arm. I had injured a knee and, feeling wobbly, used my right hand to steady me while I stood on the stool to lean over the tank. Athena in turn gripped me with only one of her arms, and very few of her suckers. Her hold on me was remarkably gentle.

Responded Humane Farming Association founder Brad Miller, “It is simply delusional to think that getting humane organizations into the business of promoting meat from heritage breed chickens will result in even the slightest reduction of animal suffering. The ASPCA decision to fund the commercial production of chickens for meat raises a number of troubling issues,” Miller continued. “Beyond the obvious ethical issues from the animals’ standpoint, there is also the matter of using charitable dollars to further the commercial interests of a privately owned, profit-driven poultry company. This is just the latest,” Miller charged, “in a growing trend on the part of several major animal organizations to, in effect, merge with the livestock industry.” Miller noted that Farm Forward has previously promoted a variety of federal and state legislation that HFA regarded as more likely to entrench the status quo in animal agriculture than to bring about meaningful change.

“A commercial animal production operation is not an alternative to factory farming, but an extension of it. In this instance, chickens and turkeys are being mass-produced in mechanical hatchery incubators, raised motherless for human consumption by the thousands, and slaughtered, i.e., factory farmed.

“In addition to cruelty and commodification of animals being falsely represented as ‘humane,’ ‘compassionate,’ ‘anti-factory farming,’ etcetera,” Davis added, “is that these relatively smaller farms seek to grow and expand. Regardless of what size they are, they do not reduce the amount of resources needed to raise and slaughter animals

“It is unethical for an ‘animal welfare’ organization,” Davis concluded, “to suggest to the public that millions and billions of people can continue to eat the same number of animals, as long as these animals are raised ‘humanely’ on non-factory farms. Humans will never set aside hundreds of millions or billions of acres of land to accommodate billions of animals living ‘free range,’ yet this is the false prospect being offered to a public that wants to believe that incompatible desires and realities can be reconciled.”

If you think it is wrong for the ASPCA to use charitable donations to fund and promote poultry slaughter, expand poultry breeding and hatchery facilities and pretend that a factory farm is Not a factory farm, while doing NOTHING to promote genuine compassion and respect for these birds,
