In the late 1990s the annual migration of the Australian Giant Cuttlefish "Sepia apama" to shallow, inshore rocky reef areas in Spencer Gulf north of Whyalla became recognized by divers and marine scientists. Divers and snorkellers can see the aggregation of animals from May through August each year, in water one to six metres deep. The most popular places to view the aggregation are Black Point, Stony Point and Point Lowly. Car parking and boardwalks or stairs to the waters edge are present at each location, making access easy.
