ScienceAustralia’s giant cuttlefish breeding spectacle suffers a 97% collapse

Only 1,811 giant Australian cuttlefish were recorded at South Australia’s Cuttlefish Coast this breeding season, down 97% from last year’s 63,000. Just 440 eggs were counted. A toxic algal bloom lasting more than 18 months may be contributing, though researchers have not established whether it caused the decline or is one factor among several.
