Whyalla’s Copulating Cuttlefish

Between May and July each year thousands of giant cuttlefish choose a remote patch of coastline between False Bay and Fitzgerald Bay near Whyalla, South Australia to aggregate and spawn. It’s estimated that this year between 150,000 and 200,000 individuals are present right now.

Biodiversity #21 – The Cuttlefish

Despite the name, the cuttlefish is not a fish, but a cephalopod (literally: ‘head-foot’) which includes close cousins squid and octopus and distant cousin: the Nautilus. Unique internal shell called a cuttlebone which, being porous it can use to regulate buoyancy. (In-built BCD!)
