8. Female octopuses lay 40,000 eggs at a time and then die

Female octopuses are truly remarkable creatures; they lay an astonishing 40,000 eggs at a time and then, after the eggs hatch and the young octopuses rise to the upper waters of the sea, the mother dies. This is a remarkable feat of maternal sacrifice, as the female octopus will not live to see her offspring grow and mature. Despite this, female octopuses are still able to ensure the survival of their species by laying such a large number of eggs.
