The dominant male is familiar to most of us: a certain type of man who always gets what he wants. And usually what he wants is sex. The female of the animal kingdom usually has the ability to choose who she has sex with, how many partners she entertains, and ultimately whose sperm her body will accept to father her young. Males have difficult obstacles to overcome in order to ensure their genetic survival. Aggression and violence are not uncommon in the animal world, but there are ways in which males have adapted to the challenges females impose. Evolution has lent a helping hand to many, so that chance is not the only factor in becoming a father. Witness how nature has enabled certain forms of sexual sabotage: male bed bugs for instance can inject their sperm into another male, so that when the latter mates, he’s actually using his attacker’s sperm. Macho Males uncovers the male’s penchant for aggression, and how his methods of courting and protecting females can be hostile, violent, and even fatal.

Nature’s femmes fatales are a presence to be reckoned with. The female Praying Mantis can and does eat her partner’s head. Although that doesn’t stop the male. His body takes over and he continues to service her, hoping for the smallest chance to continue his family line. Watch how these femmes fatales command the males of the animal world to obey their every whim. They push the males’ limits and comfort zones to extremes, sometimes with disastrous consequences. For the male, at least.

If animals don't advertise their sexuality through strength, they have to find other selling points. And millions do. The natural world is full of shameless self promoters using sexual signals which work on every level, and attack every sense.
