Deadly octopus bites woman multiple times on Sydney beach

Paramedics arrive at a Sydney beach where a woman was bitten by a blue-ringed octopus.

A 30-year-old woman was stabbed multiple times in the abdomen at Chinamans Beach at around 2.45 pm.

Blue-ringed octopuses are among the world’s most venomous marine animals, containing enough venom to kill 26 adult humans in minutes.

Due to their size, octopus bites are small and often painless, but their venom can cause respiratory arrest, heart failure, paralysis, blindness, and eventually death from suffocation.

Octopuses are relatively docile, only showing their bright blue rings and becoming dangerous to humans when threatened.
