Bite and Symptoms
Blue-ringed Octopus are normally not aggressive and attack only
when provoked. They are, however, the most venomous octopus
in the world and the salivary glands of one individual may contain
enough venom to paralyse ten men. The actual bite is often relatively
painless and may go unnoticed. If sufficient venom has
been introduced (sometimes little venom may enter the wound if
the attack occurs under water), the victim will notice numbness
or tingling around the face and neck within a few minutes.
Difficulty in seeing or speaking is often followed by trouble with
breathing and sometimes vomiting. Weakness and lack of coordination
usually progress to paralysis, which may last from four
to twelve hours. If resuscitation is not given when breathing difficulty
and paralysis begin, the victim will fall unconscious and die
from lack of oxygen. Death can occur within thirty minutes.
