Octopuses, crabs and lobsters are capable of experiencing pain or suffering, as indicated by a survey authorized by the UK government, which has added the animals to a list of sentient beings to be given protection under new animal welfare laws.
The report by specialists at the London School of Economics checked out 300 scientific studies to assess proof of consciousness, and they presumed that cephalopods, (for example, octopuses, squid and cuttlefish) and decapods (like crabs, lobsters and crawfish) ought to be treated as sentient beings.
Vertebrates, animals with a spine, are now classified as sentient in new animal welfare legislation currently under debate in the United Kingdom.
“The Animal Welfare Sentience Bill provides a crucial assurance that animal wellbeing is rightly considered when developing new laws.
The science is now clear that decapods and cephalopods can feel pain and therefore it is only right they are covered by this vital piece of legislation,” said Animal Welfare Minister Lord Zac Goldsmith in a statement.
The Bill, which isn’t yet law, will set up an Animal Sentience Committee, which will investigate how well government decisions have taken into account the welfare of sentient animals. It is important for a more extensive government Action Plan for Animal Welfare.
The report used eight distinct ways of estimating consciousness including learning capacity, possession of pain receptors, connections between pain receptors and certain brain regions.
It included the response to anesthetics or analgesics and behaviors including balancing threat against the opportunity for reward and protection against injury or threat.
It found “extremely strong” proof of sentience in octopods and “solid” proof in many crabs. For other animals in these two groups, such as squid, cuttlefish and lobsters they found the evidence was substantial but not strong.
However, the report said these varying degrees of evidence reflected disparities in the amount of attention different animals have received from scientists.
“Scientific attention has gravitated towards some animals rather than others for reasons of practical convenience (e.g. which animals can be kept well in labs) and geography (e.g. which species are available where a lab is located).
Because of this situation, we think it would be inappropriate to limit protection to specific orders of cephalopod, or to specific infraorders of decapod,” the report said.
The recent Netflix documentary “My Octopus Teacher” showcased the unique abilities of octopuses.
The brain structure of octopuses is very different from that of humans, but it has some of the same functions as mammal brains, such as learning abilities, including being able to solve problems, and possibly the ability to dream.
