How Could We Know If an Octopus or Lobster Felt Pain?

Researchers found that, when it comes to awareness, octopuses were the stars, followed by lobsters, crayfish, crabs, etc.

Some researchers, commissioned to find out, offered their wrap-up thoughts at Phys.org recently. They started applying the same standards to octopuses as are applied to mammals that are lab animals. Specifically, they used eight criteria for determining sentience — in the sense that, if you did the same thing to a dog and got the same reaction, would you assume it was pain? The results have been interesting: We found the strongest evidence for sentience in cephalopods. Octopuses were the stars. With around 170 million brain cells, they have higher brain-to-body ratios than most reptiles and fish. This allows octopuses to perform remarkable feats of learning and memory. Octopuses also behave in ways that point strongly to experiences of pain.…

British Government Moves To Protect Octopuses From Cruelty

The move to protect cephalopods and crabs/lobsters follows from research showing their intelligence and awareness of pain

Following a report from the London School of Economics and Political Science, the British government has decided to extend animal protection laws to include “cephalopods (including octopuses, squid and cuttlefish) and decapods (including crabs, lobsters and crayfish).” No, this is not just another nut moment along the lines of “Salad is plant murder!” There’s a background: Researchers have discovered in recent decades that some invertebrates, especially those with complex central nervous systems, are much more intelligent and capable of experiencing pain (sentient) than we used to think. As George Dvorsky explains at Gizmodo, the British government introduced the Animal Welfare (Sentience) Bill in May. The bill defined sentient animals as animals with backbones (vertebrates). However, scientists have known for some…
