Which Species Die—or Kill—for Love?
We’ve all seen those beautiful penguin photos, beaks together forming a heart, on Valentine’s Day. And don’t get us wrong; we love how adorable and sweet nature can be. But just for fun, we thought we’d explore the darker side of love in the wild—with animals that are willing to die for it! Maybe they’ve been listening to too much Prince: “You just leave it all up to me; my love will be your food.”
Is all fair in love and war? Find out which sex comes out on top …
Honeybee—The Virgin Queen
Here’s how it goes down as the queen flies to a new location: The males mount the queen in flight, insert their endophallus, have it ripped from their bodies and die leaving the queen newly fertilized. Oh, honey!

Praying Mantis—Off with His Head!
Females usually kill their mate when he dismounts after copulation (although sometimes she starts during the act)—starting with the arms so he can’t fight her, next with the head and on down. Half of all males successfully dismount without harm. It all comes down to how hungry she is. How’s that for a dinner date?

Black Widow—Kiss of Death
Females frequently eat their male partners before and after mating, and her venom is at least three times more potent than his, making a male’s self-defense bite ineffective. His best bet? Pluck a few strands of her web to see if she wants to mate, and if he goes for it, be ready to web hop!

Brush-tailed Australian Marsupial Mouse—Bop ’til You Drop
This mouse wastes no time finding a mate, becoming sexually active by age one. The males die two weeks after breeding due to the stress and exhaustion of mating, leaving the female a single mom caring for her young.

Most adults live two hours to three days, but some live less than 90 minutes. In that time, they need to mate, deposit the female’s eggs and die. Talk about a one-track mind!

Fairy Shrimp—Short but Sweet
Is it all about the kids? Fairy shrimp mate and fertilize their eggs in temporary rain pools. They die when the water dries up, leaving their offspring to wait in the soil for the rains to return, starting the short and unselfish cycle again. Now that’s taking one for the team.
