How Lurking Predators Changed the Size of the Mosquitofish's Genitals

Female mosquitofish give birth to tiny babies, like the guppies you may remember from your third-grade aquarium.

The Unusual Mating Habits of This Octopus Totally Blow Biologists' Minds

We all know the sad story of octopus sex, right? They live alone until it’s time to find a mate, they have sex a few times, then the males die.
