Sexual arms race

The Natural History museum has a fascinating news story about sexual arms races in diving beetles.

Apparently, every time male diving beetles evolve better suction cups on their feet to hold on to females during mating, the females evolve countermeasures to decrease the effectiveness of the suction cups. This is because the optimal time, length or the number of matings is not the same for males and females.
