How long does it take for an octopus to get pregnant?
The eggs might incubate anywhere from
two to 10 months

Why is octopus lifespan so short?
Octopuses have a relatively short life expectancy; some species live for as little as six months.
Octopus lifespan is limited by reproduction
: males can live for only a few months after mating, and females die shortly after their eggs hatch.
Do octopus babies eat their mother?

What is the lifespan of an octopus in captivity?
It varies according to species, but octopuses, both wild and captive, live roughly
1 to 5 years

How does a female octopus get pregnant?
Octopus vulgaris has individuals of both sexes.
During mating, the male approaches the female, who fends him off for a while, but then accepts him

What percentage of octopus eggs survive?
In the wild, the survival rate of hatchlings is about
1 percent
. In an aquarium, the odds of survival are very low as the hatchlings are extremely delicate and have complex nutritional needs. This is ASLC’s third opportunity to raise Giant Pacific Octopus babies and staff remains hopeful as they begin rearing.
