To learn about the giant cuttlefish spawning aggregation and the experience of seeing and filming them, check our blog http://www.oneworldoneocean.org/blog/entry/ocean-stemulation-from-squid-skin-to-smart-clothing
Giant cuttlefish (Sepia apama), photographed by renowned underwater filmmaker Howard Hall, gather off of Whyalla, South Australia to spawn. Males display mating colors and compete aggressively to mate with females.
The giant cuttlefish is the worlds largest cuttlefish species. They gather in large numbers to mate. During that time, large males compete aggressively for females and small males tend to approach potential mates sneakily. They can mate only once in their lives and the females will die not long after laying eggs.
Cuttlefish and other cephalopods are remarkable for their ability to change their skin color and texture.
Chromatophores, cells containing pigment, can rapidly expand or contract to reveal different colors and patterns. To learn more about how cuttlefish change their skin color, visit this page: http://www.oneworldoneocean.org/field-reports/entry/diving-with-the-worlds-largest-cuttlefish")
