The report by experts at the London School of Economics reviewed 300 scientific studies to assess the evidence for credibility, and they concluded that cephalopods (such as octopuses, squid and cuttlefish) ) and scavengers (such as crabs, lobsters and crayfish) should be treated as living beings.
Vertebrates, vertebrate animals, have been classified as sentient in the new animal welfare law currently being debated in the UK.

The report used eight different ways to measure resilience including learning ability, possession of pain receptors, connections between pain receptors and certain brain regions, response response to anesthetics. or pain medication, and behaviors that include balancing threat with opportunity for reward and protection against injury or threat.
It found “very strong” evidence for submission in octopuses and “strong” evidence in most crab. For other animals in these two groups, such as squid, cuttlefish and lobsters, they found the evidence to be substantial but not strong.
However, the report said the The different levels of evidence reflect the disparities in the amount of attention different animals have received from scientists.
“Scientific attention has been focused on some (animals) rather than others for reasons of practical convenience (e.g. which animals can be grown well in a laboratory) and geography (e.g. what species are available where the laboratory is located) Given this situation, we consider it inappropriate to limit protection to specific orders of cephalopod species or organisms decapod-specific infrastructure,” the report said.
