Australia’s tropical savannas are home to an enormous number of invertebrates — animals without backbones — and we’re not just talking about flies and mosquitoes. Ants and termites, for example, are very abundant in northern Australia and play a significant role in ecosystems. Termites are probably the most conspicuous insects in northern Australia building countless earthern mounds or 'anthills' that can dominate the appearance of some landscapes in the tropical savannas. These insects are also important decomposers as they can consume dead grass and wood throughout the harsh dry season when many other decomposing organisms struggle to survive.
