Summary
More than 200 marine species off the coast of South Australia have died due to a toxic algal bloom, which has spread to about 4,500 sq km since March, described by conservationists as “a horror movie for fish.” The algae produce toxins that suffocate marine life, including sharks and rays, with reports of graphic hemorrhaging among affected species. While the bloom isn’t harmful to humans, it has impacted local fisheries and tourism, prompting the government to advise against swimming in affected areas as researchers monitor its westward movement.
