The Australian Giant Cuttlefish aggregation is truly one of nature’s great events. Thousands of cuttlefish congregate in the shallow waters around the Spencer gulf in South Australia, to mate and perpetuate the species. The cuttlefish like alien beings, display an array of patterns, textures and colours to indicate their intentions. As male courts a female or wards off other males, and entourage of suiters stay poised for an opportunity to mate with the female. A visual delight and a rare glimpse of nature in all its glory.
