Although male submission is rare in the animal kingdom, species such as bonobos, octopi, honey bees, lemurs, hyenas and topi antelopes have males that are submissive to their female counterparts. Some instances of submission occur in reproductive practices, grooming, feeding and sleep site priority.
The male ceratioid anglerfish is another species that is submissive to the female. The male has a parasitic relationship with the female anglerfish, and his survival is completely dependent on his ability to attach himself to a female anglerfish for nourishment. When the female is ready for reproduction, the male's sole purpose is to fertilize her eggs.
