During the mating, the male enters the female’s mantle with a very flexible, long arm (the hectocotylus) and delivers its sperm. The female then retrieves in her den and lays tens of thousands of eggs. The female takes care of the eggs by blowing fresh water over them. During this time, she can not eat herself. After a month, the eggs hatch and the female dies of exhaustion. The male has already died, shortly after mating. The baby octopuses have to take care of themselves now. Data on the behavior of octopuses mainly come from aquarium studies. In the wild, it is very difficult to study the octopus. They can camouflage themselves well or simply hide. The Abdopus aculeatus is not a unique kind of octopus. It is possible that other octopuses will show the same behavior.
