Australian giant cuttlefish population crashes to historic low at Point Lowly

The giant cuttlefish aggregation at Point Lowly, South Australia, has suffered a dramatic collapse in 2026, with fewer than ten individuals observed per dive. This marks a steep decline from a previously recorded gathering of around 100,000 cuttlefish. Researchers suspect a recent algal bloom in the region may have harmed the cuttlefish directly or depleted their food sources. In response, authorities have introduced conservation measures and suspended tourism activity at the site to aid population recovery.
