The Ecology of Octopuses

Giant cuddle fish are as intelligent as us, but they can't pass the knowledge onto the next generation. The male octopus will hand over the sperm via a specialised organ to the female, who then lets it go into a reproductive place in her body. They have organs called chromatophores and primitive vision. And I've seen videos of a cuttlefish copying a chessboard. How do they change? So I definitely don't know. We need a marine biologist to tell us.
