Octopuses display remarkable cognitive complexity and pain responses - growing evidence of sentience has welfare implications for both wild and captive populations.
Octopus sentience evidence has grown sufficiently strong that regulatory change has followed. The inclusion of cephalopods in UK sentience protections reflects scientific consensus that octopuses have sufficiently complex nervous systems to warrant precautionary welfare consideration. This has implications for research, aquaculture (where octopus farming is growing), and fishing practices. Supporting research into octopus cognition and welfare standards for captive cephalopods is at the frontier of animal welfare science.
