We do not speak to each other, because we know too much
Mating can be dangerous. At least 100 years ago, biologists began to speculate that sex in the animal kingdom could be a very risky business. The noises can attract predators, the male is distracted and he has less energy to fight off an attacker or to run away. Perhaps that is why males almost always attempt to finish so quickly. Surprisingly, however, there has been little evidence to support this hypothesis until recently. Two lab studies and one in the field have shown that mating increases the risk of predation in freshwater amphipods, water striders and locusts.
Now a new study shows very strong evidence of the effect in flies.
