Dozens of dead fish, including threatened species, have washed ashore local Australian beaches, all attributed to a massive toxic algae bloom.

An Australian state closed two beaches after dead fish and an unusual off-white foam washed ashore while surfers reported feeling unwell, officials said on Tuesday. A microalgal bloom created by unusual weather conditions was suspected to have sickened humans and marine life as well as creating the foam that has covered hundreds of metres of coastline,

A microalgal bloom created by unusual weather conditions resulted in foam covering South Australian beaches. Dead fish are also washing ashore and beachgoers are reporting feeling sick.
