The peacock spider (Maratus volans) may only grow to about 5 millimetres long, but it puts on one of the most spectacular courtship displays in the animal kingdom. It's just one of more than 100 known species of peacock spider found across Australia, each with its own unique colours, patterns and dance moves. During courtship, males raise their brightly coloured abdominal flaps like a tiny fan and perform an energetic dance, waving their legs and vibrating their bodies in the hope of impressing a female. The performance has to be just right—if she isn't impressed, she may decide he'd make a better meal than a mate. Protecting healthy native bushland helps support these tiny predators and the countless other small creatures that share their habitat, and organisations like Invertebrates Australia advocate for the conservation of Australia's often-overlooked invertebrates. At just a few millimetres long, the entire dance could fit on your fingernail—yet it's dramatic enough to rival any wildlife documentary.
