Paramedics have rushed to a Sydney beach where a woman was bitten by a blue-ringed octopus.
The woman in her 30s suffered multiple bites to her stomach about 2.45pm at Chinamans Beach.
Blue-ringed octopuses are among the world’s most venomous marine animals, carrying enough venom to kill 26 adult humans within minutes.
Because of their size, the octopuses’ bites are tiny and often painless but their venom can cause respiratory arrest, heart failure, paralysis, blindness and eventually death from suffocation.
The octopuses are relatively docile, only showing their bright blue rings and becoming dangerous to humans when threatened.
