On World Jellyfish Day, observed on November 3, the report highlights creatures that date back around 700 million years. Most have neither a brain nor a heart, and their stings cause about 150 million injuries each year; the venom of the Australian box jellyfish can be fatal within three minutes. Among their remarkable features, the “immortal jellyfish” can return to the beginning of its life cycle, one lion’s mane jellyfish measured 30 metres across, and some species glow in the dark. A study by India’s University of Madras found that jellyfish venom killed lung and liver cancer cells within two days without harming healthy cells, though more research is needed before it can become an approved treatment. If stung, the report advises leaving the water, applying vinegar or salt water to the affected area, removing any remnants while wearing gloves, and then soaking the area in warm water for about 20 minutes. Painkillers may be used if needed.
