Story summary
- South Australian Department of Environment and Water reported 1,811 cuttlefish at Cuttlefish Coast, a 97% decline from 63,000.
- The department attributes the collapse to a toxic algal bloom that has persisted for over 18 months.
- Divers led by 28-year-old diver Manny Katz found only about 440 eggs along eight kilometres of reef, versus millions.
- Co-founder Stefan Andrews urges listing the Australian cuttlefish as threatened because adults are still laying eggs.
