No, we're not insulting the fish.
It literally has a penis on its head.
Not like on top, like some sort of perverted unicorn sent down to pleasure/terrorize mankind.
The penis hangs under its chin.
It also has a rod and jagged hook as part of the genitals so it can more easily attach itself to the female during sex.
That sounds terrifying.
The female's sex organ is under her chin as well so we guess they kinda just butt heads until babies are made.
Thank goodness we're not fish.
