Octopus populations have been booming in the past 60 years to the point where some marine
biologists even call them "the weeds of the sea."
Their main purpose in life is to breed and make babies, but the way they do that is real
weird.
Check out this Facebook video we made to
see how... octopuses? Do the dirty.
The octopus has 8 tentacles
And in the male, one of those tentacles is also
a penis, well, sort of
This is the hectocotylus
A specialized mating arm, with a groove that runs along tentacle
carrying packets of sperm to be distributed from the tip
Should that special moment arrive
Most octopuses live solitary, antisocial lives,
hunting and scavenging for food along ocean floor.
However, when the time arises, they mate in a very intimate way.
The male must deposit its sperm into a hole in the female's mantle
a hole that she uses to breathe and expel waste
Or as Aristotle romantically described: "the Nostril of the Female."
In a vast and sparse ocean, the opportunity to procreate is rare
and for most octopus species, it will be the last thing they ever do
because for male octopuses, the prospect of mating is a dangerous one.
You see, the female is often larger, hungrier, oh, and cannibal
So, in order to protect himself, he must make a careful and considered approach
For longer armed octopuses, the move of choice is The Reach
To keep their distance from the cannibal female
the male will stretch his mating arm as long as possible,
keeping the distance while he copulates.
Some species will even wait until the female is foraging for food
and therefore too preoccupied to eat them
And some species have evolved beyond "the reach"
More cautious males will simply detach their mating arm and give them to the female.
The hectocotylus will stay intact in the female's mantle until the female is ready for fertilization
Once the copulation is complete, the octopuses' life mission is complete
Both male and female will experience a dementia-like state of being after mating called: senescence.
The male will experience this alone.
They do not eat or return to their dens, and will eventually die from their weakened state.
The female will devote the rest of her days to her eggs
ensuring that her thousands of offspring hatch before dying of exhaustion.
This unconventional courtship will create 56,000 eggs.
And because the yield is stable, only 2 will survive to maturity
Pretty crazy right? Those poor little guys. If you
wanna know more about how animals get it on, check out our series “Wild Sex” on Seeker’s
Facebook page, Seeker Media.
In the meantime, if you’re curious what happened after ancient humans and neanderthals
had sex, watch this video here.
Are there any other weird animals you want to know more about?
