Signs and symptoms of blue-ringed octopus bite
Blue ringed octopuses secrete a nerve toxin in their saliva. Their bite is usually painless, but the person bitten will feel numb around the mouth, tongue, face and neck and will feel tight in the chest and may have difficulty breathing.
Respiratory failure occurs eventually which leads to death if the person is not resuscitated. Most of the time, the victim is aware, but unable to move or respond.
