Octopus under threat

Octopus is considered a delicacy - grilled, boiled, or fried. But rising demand has consequences, and in several regions of Europe, this intelligent cephalopod is already considered overfished. The ecological consequences of octopus overfishing are already visible: in Italy, the invasive blue crab is spreading uncontrollably. It is one of the octopus's favorite foods - but without natural enemies, it is now destroying mussel farming in the Po Delta and thus posing a threat to livelihoods.
