7. Female honey bees call all the shots. The honey bee caste system is extremely matriarchal, with the queen and worker bees all being female.

The kicker? Male bees are actually referred to as "drones."
8. Topi antelopes aren't afraid of being dominant. It is rare that the females in the species have a more ravenous sexual appetite than the males, but that is exactly the case when it comes to the Topi antelopes. Topi antelope females are only fertile one day per year, and during that 24-hour period they essentially hound the male antelopes to the point of exhaustion. These antelopes exhibit sexual behavior that is counter-stereotypical in that the females are the aggressors and the males tend to be more stand-offish.
9. Female anglerfish wear the pants in the relationship. In many species of ceratioid anglerfish, it is common for the (much smaller) male to attach himself to the lady anglerfish and proceed to atrophy until he is essentially a parasite with male reproductive organs, available to the female whenever fertilization is needed. A male anglerfish will not sexually mature until he finds a female to parasitize, and if he does not find one he will die...
