Asked at “The Scientist”: Do Invertebrates Have Feelings?

Just as vertebrates differ greatly in intelligence and sentience, invertebrates may differ greatly too. The seafood industry is taking heed.

People did not ask this question about invertebrates like bees and snails fifty years ago: Decades ago, scientists and lawmakers had all but reached a consensus that invertebrates could not feel pain, let alone other emotions like joy or fear. Recently, however, evidence is mounting that invertebrates are more than just reflexive beings. Experiments in bees, crabs, and octopuses show that some invertebrate animals can learn from painful experiences, have positive and negative emotion-like states, and might even experience a range of other emotions beyond pain and pleasure. But not all scientists agree that invertebrates feel anything analogous to vertebrate—much less human—emotion. Natalie Mesa, “Do Invertebrates Have Emotions?” at The Scientist (May 26, 2022) Assessing the evidence is tricky. In…

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…
