I.
Due a mild winter followed by an exceptionally warm spring, record numbers of octopuses have abandoned their Mediterranean homes and taken up residence along England's south coast.
So many in fact, that approximately 233,000 were caught in UK waters this year - over ten times the average amount - and 2025 has been declared as the year of the octopus by the Wildlife Trusts in their annual review of what's going on in the marine world.
This is not entirely unprecedented, however: a sudden increase in the population of the common octopus - known as a bloom by teuthologists and cephalophiles such as myself - was also observed in 1950 and, prior to that, in 1900.
This is, on balance, welcome news (although not if you're a Cornish lobster or Devon crab) and I find it comforting to imagine a time - long after the extinction of man - when octopuses rule the world; a future possibility that, whilst speculative in nature, is one that many scientists are taking increasingly seriously ...
II.
Tim Coulson, for example, a professor of zoology at the University of Oxford, argues that if humanity were to fall into the evolutionary void, then the octopus, thanks to its physical and mental attributes, is in pole position to become the dominant species on the planet.
For these eight-legged animals are not only highly intelligent, but also possess, says Coulson, the dexterity, curiosity, and ability to communicate with each other that may one day allow them to make complex tools and, who knows, build a deep-sea civilisation [2].
Coulson even advances the possibility that octopuses might - under the right circumstances and environmental conditions - eventually evolve into animals capable of spending at least some of their time on land in a post-human (and, in all likelihood, post-mammalian) world, although the lack of a skeleton and lungs with which to breathe would obviously be serious hurdles to overcome.
As mentioned, this is all highly speculative and we've really no way of knowing what evolutionary surprises the future will produce millions of years from now.
But it would be unwise to bet against the octopus playing some part in this future; for this is a creature with an evolutionary history behind it stretching back to a time pre-dating the dinosaurs, so they're obviously adaptable and prepared to play the long game.
And I for one say better a world of octopuses than a world of intelligent machines ...

[2] This isn't as far-fetched as some readers might think; there are, in fact already two established octopus settlements that we know of; Octopolis (discovered in 2009) and Octlantis (discovered in 2016).
While the latter was constructed entirely from natural materials (sand and shells), the former incorporated scrap metal into its design. Both are located in Jervis Bay, New South Wales, Australia, and are home to a small number of gloomy octopuses (Octopus tetricus). The existence of these sites challenged the previous belief that octopuses were solitary creatures and revealed a surprising level of social interaction, as well as environmental engineering.
