Nature (1982)

Season 26: Episode 10

Apparently, there is nothing a male will not do for the right to mate with a female — dance, sing, fight, change body colors, illuminate, even agree to be eaten alive. There is often a surplus of males, and they are instinctively driven to compete in order to pass their genes to the next generation. But it takes two to tango. Now, scientists are learning to what extremes males will go in order to find that dance partner.
