Heating Oceans Will Make the Octopus Myopic?

The octopus is the Earth's most cerebral invertebrate. These species are also very dependent on vision. There's recent evidence, however, that global heating will impair this sense, as well as reduce octopus survival (https://www.theguardian.com/environment/2024/apr/10/octopus-eyesight-loss-ocean-temperatures-global-heating). An Adelaide University study exposed 'unborn' octopuses and their mothers, to temperatures of 19; 22 or 25 degrees Centigrade. Nineteen degrees was selected as a 'control', whereas 22 degrees represented Australian summer ocean temperatures. The 25 degrees value, was a presumed match summer water temperatures in 2100. Octopus, exposed to this highest temperature, produced much less of the protein responsible for the production of visual pigment in octopus eyes. The rates of unborn offspring and premature deaths of pregnant mothers, were also highest at this temperature. It seems very likely that climate change will challenge octopus survival in many parts of the world's oceans. They are consequently unlikely to be around, to take over, if humans 'autoextinct' themselves.
