No Way to Treat an Alien Intelligence?

Cephalopods (octopus, squids and their relatives) are, by far, the most intelligent of the invertebrates (animals without backbones). Unlike, however, vertebrates these molluscs have failed to attract significant animal welfare protections. Cephalopods appear disadvantaged because they seem almost 'alien' to humans. They use their chromatophores (quickly changing skin pigment cells) to signal to eachother. A squid can, for example, simultaneously signal different things on the left and right hand sides of their bodies (politicians would love to have this skill). Octopuses and squids also don't use sounds that, in mammals, can elicit human pity. It seems rather sad, however, that there are now proposals to farm octopuses for the human table (https://www.theguardian.com/environment/2023/jun/25/a-symbol-of-what-humans-shouldnt-be-doing-the-new-world-of-octopus-farming). One obvious difficulty with octopus farming, is that it's very difficult to know how to environmentally enrich such animals. We really don't know what they 'want'. Certainly, keeping such intelligent animals in vats with lids, 'aint going to do much for their welfare.
