But the aggravated crustacean immediately jumped onto its back and fended off the venomous octopus by repeatedly striking its tentacles.

What are blue-ringed octopuses?
The blue-ringed octopus bite is highly venomous to humans and emergency services should be called immediately if it occurs.
Blue-ringed octopuses are not aggressive animals and most cases of bites are from a person picking up and handling the creature, or stepping on it.
Danger to humans:
It injects its toxin by biting – the venom is held in salivary glands and the mouth of the octopus in on the underneath side in the middle of the body.
Most bites cause minimal pain for the first 5-10 minutes then begin to throb and may get numb.
The bite could cause excessive bleeding, nausea, vomiting, changes in vision and difficulty swallowing.
After 10 minutes, the victim may have difficulty breathing, become paralysed, and require artificial ventilation until they can be transported to a hospital.
The duration of life-threatening symptoms is usually four to 10 hours – after that time, surviving patients typically show rapid signs of improvement.
There is no anti-venom available for blue-ringed octopus bites.
