Gender imbalance

The death of thousands of goldfish in the ponds of Britain in the spring of 1977 has been attributed to sex-crazed toads. That spring, male toads found themselves in a ten to one majority over female toads. The resulting dearth of breeding partners left the males mating with anything: water-lilies, sticks, and also pets. The grip of a mating male toad is easily sufficient to crush an average goldfish.
