The Australian continent is characterised by having a somewhat irregular climate. Droughts lasting for many years are not
uncommon and any farmer who relies on the coming of the rain is going to have to learn, sooner or later, that the rains don't
always come. It might come as a surprise to some people but over much of inland Australia the greatest biomass of vertebrate
fauna is comprised of frogs. Frogs of the genus Cyclorana are capable of remaining buried beneath the ground for up to seven
years, if necessary, before emerging to breed and feed (not necessarily in that order).
