There is a wealth of research that suggests octopuses are one of the most complex and intelligent animals in the ocean. They can recognise individual human faces, solve problems (and remember the answers for months) and there is some evidence they experience pain and suffering. They are the only invertebrate that the 2012 Cambridge Declaration on Consciousness considers sentient alongside mammals and birds. They are also a culinary delicacy with growing demand, but scientists say farming them is not only unethical but extremely damaging to the environment.
