Australia's coastal battleground is home to thousands of marine animals who compete for food, territory and the right to mate.
The Australian desert is one of the most exposed areas on the planet, a vast battlefield that tests its wild warriors as much as they challenge each other in the battle for survival.
Forests are places of opportunity: they provide shelter, water, and food - for both predator and prey. But opportunity brings competition, and with so many creatures concentrated in these areas, conflict is unavoidable.
Swinging between blistering, dry heat and violent flooding storms, the wetlands of tropical north Australia are as difficult to contend for the competing creatures that inhabit them.
