It's an angler fish.
One of the ugliest animals ever, Anglerfish look really pissed off all
the time (maybe it’s because they live in the dark at the lonely bottom
of the sea). Their heads are enormous, with teeth that are sharp and
translucent.
The female sports a piece of dorsal spine that sprouts out
of their head above her mouth like a fishing pole. The tip is luminous
and attracts bait.
The male is way smaller by comparison and has no need
for the “fishing rod.” With his sharp teeth he latches onto the female
and fuses with her. He connects to her skin and bloodstream and loses
his eyes and all his internal organs except his testes. Ew, that’s a lot
to lose for love.
