Coastal peacock spider

Maratus speciosus, sometimes called the coastal peacock spider, is an Australian species of jumping spider (family Salticidae). They are only known to inhabit the vegetation of the coastal sand dunes of southwestern Western Australia. Like other Maratus spiders, the males of the species engage in a courtship display during which they raise their third pair of legs and their abdomen, presenting their colorful opisthosomal plate to potential female partners. Unlike other Maratus, however, the males of this species have a set of bright orange hairs (setae) along both edges of the opisthosoma which only become visible during this display.
