Many fish will shift sexes across a lifetime, so they're called sequential hermaphrodites.
But the ones that are maybe making both sperm and eggs in their body at the same time are classified as simultaneous hermaphrodites in science.
So Kay Holkamp is the scientist I'm obsessed with.
She's based out of Michigan.
She inherited and now runs, she's been running for 40 years, the longest running spotted hyena study on the Massamara.
And they have like these amazing like real housewives of the Massamara, like dynastic maps of the hyena hierarchies because they're really tightly run.
The alpha female, they're in a matriarchy.
The alpha female is dosing her babies with androgens.

She was like, I've never seen an animal be born fighting like that.
But the alpha female's daughters are defending their rank Tudor style from the day they're born.
But what happens is scientists will be in the field and they will be sexing hyenas who seem to have penises.
Yeah.
So they're building their map of like, this is this community.
That one's interacting with that one.
