Toxin on the Beach: The Silent Killer in Australia's Oceans The mass death of hundreds of thousands of marine animals off South Australia's coast last year has highlighted the fragility of our planet's ecosystems.
Research published in Nature Ecology & Evolution confirms that Karenia cristata, a microalgae found in cold waters, can unleash devastating neurotoxins on marine life.
The die off was unprecedented, with thousands of fish, seahorses, octopuses, and even birds falling victim to the algal bloom, which lasted several months.
