Something strange is happening in the South Australian seas. Someone’s not turned up for their party. Around this time of year the Australian giant cuttlefish (Sepia apama) gather along the South Australian coastline between False Bay and Whyalla to mate and spawn. Why has it happened? Have they found a new place to get together? Or, are there so few of them now that it’s a big deal to see three or four in the one place? Will they come back? Is it natural, or something us humans have done?
