How long do octopus mate?
The male first "mounts" the females mantle, then inserts the hectocotylus, an arm that acts as a "tube", to allow the sperm to enter the female's oviduct. This lasts around half an hour. O. briareus usually mates during the day and only the male octopus can initiate or stop the mating process. After the female octopus has been fertilized, she can store the sperm in her oviduct for at most 100 days. After finding a suitable lair, the female then lays eggs. Some females have been known to seal themselves in their lair while pregnant. A female can lay up to 500 eggs; clusters of eggs are joined by special stalks. The female then sits with her eggs until they are ready to hatch. If any creature comes near the eggs, the female will attack it, though if it kills the creature, will not eat it. The eggs take 50 to 80 days to hatch, but will hatch more quickly in warmer waters. Newly hatched young are able to jet propel themselves round and squirt ink, much like their parents. In just 14 weeks, the hatchlings are 75% of their full-grown size and in just 140 days, male hatchlings reach sexual maturity, and 150 days for females.
