Maratus is a spider genus of the Salticidae family (jumping spiders). These spiders are commonly referred to as peacock spiders due to their colorful abdominal flaps that they display during courtship. In at least one species, Maratus vespertilio, the expansion of the flaps also occurs during ritualized contests between males. All described species, except M. furvus, are endemic to Australia. Maratus live on the ground or in low bushes.
