It really is.
Not everyone does it, right?
There's definitely even many snakes and lizards that are capable of asexual reproduction.
There's many lizard species and at least one snake species where it's obligate, right?
There are no males.
only females, and so they just reproduce clonally.
Where they still have the behaviour, copulatory behaviour of one female.
with another and that stimulates ovulation, but there's no sperm transfer because there's no sperm to transfer.
Scorpions don't have a penis, right?
They have something called a spermatophore.
It's detachable.
Basically, they dropped it on the ground, and then in that male-female dance that scorpions do, they pull the female over it.
And it gets more interesting than that, Anne, because males often sting the females during that.
No.
It's called sexual sting in the venom gland of males.
Quite likely that it also produces chemicals that help the male's interest.
And then in that male-female dance that scorpions do, they pull the female over it.
And that goes inside the female, and the tip of it has sperm, which goes inside the female, but it also normally breaks, and the tip of it serves as a mating plug.
Doesn't come out to female until she has babies.
So he guarantees she can't mate a second time.
