 The text discusses how octopuses have controlled direction in their brains, which is independent of their body. It also talks about how male octopuses have detachable penises that they use to mate with females, and how this process can be repeated multiple times. Additionally, it mentions that female octopuses can store sperm from multiple males and choose which one to fertilize their eggs with. The text also touches on the topic of tourism in Florence, Italy, stating that around 16 million tourists visit the city every year, and how this has led to concerns about overcrowding and the impact on the local economy.
