ARISE SQUID OVERLORDS! grow faster and reproduce more), and less fish may mean less predators around to eat them and fewer competitors around to battle with. What does this mean for us? “I for one welcome our cephalopod overlords” - Washington Post, 23rd May 2016 “What exactly do people find so unsettling about a dramatic rise in the population of tentacled geniuses?” - The Onion, 25th May 2016 Cephalopods, and their supremacy in the deep sea, are steeped in mythological intrigue and popular culture – think the Kraken from the Norse legends, HP Lovecraft’s Cthulhu, and the sea monsters conjured up by Jules Verne and Victor Hugo. When our study hit the international media in May this year, everyone, from major newspapers to satirists to bloggers, seemed to have RESOURCES an opinion about cephalopods and what their booming numbers would mean for us. So let’s cut to the chase – what does it mean? Cephalopods are a large and diverse group of animals that inhabit all marine habitats. They are voracious and adaptable predators, an important source of food for many marine species (such as marine mammals, fish, seabirds) and support many important commercial and subsistence fisheries around the world. So depending on your point of view an increase in cephalopods could be a good or bad thing. However, we don’t really know what effect cephalopods are having on the oceans and we don’t really know if cephalopods will keep increasing in number (it’s possible that they may just turn to cannibalism when they run out of food!), so at this stage we can just speculate.
