In this excerpt from the BBC/Discovery documentary Life, we learn about a mating strategy that's fairly common in the animal world. A female cuttlefish is courted by two males. One is large and dominant, fighting off other males in order to fertilize the female's eggs. The other is what's known rather judgmentally among zoologists as a "sneak," a small cuttlefish who changes his color and appearance to look like a female. Pretending to court the large male, he snuggles up next to the female and secretly mates with her. Obviously, the female likes both kinds of attention, since she chooses to accept both males and fertilizes her eggs with both their sperm.
