A 17-year-old Queensland boy has died a week after being stung by a box jellyfish, the first box jellyfish death in Australia in 14 years.
From deadly snakes and spiders to the box jellyfish and blue-ringed octopus, Australia’s legendary range of venomous creatures is being celebrated as a potentially rich source of new drugs and disease treatments.
Venom is commonly measured by the LD50: the concentration of toxin (lethal dose, mg/kg) required to kill half of a test animal group. A smaller number indicates more concentrated venom, with the most venomous species gaining a rating of <1. These are Australia's most venomous animals, ranked by their LD50 rating.
