Blue Ringed Octopus: The bite might be painless, but this octopus injects a neuromuscular paralysing venom. The venom contains some maculotoxin, a poison more violent than any found on land animals. The nerve conduction is blocked and neuromuscular paralysis is followed by death. The victim might be saved if artificial respiration starts before marked cyanosis and hypotension develops. The blue-ringed octopus is the size of a golf ball but its poison is powerful enough to kill an adult human in minutes. There’s no known antidote. The only treatment is hours of heart massage and artificial respiration until the poison has worked its way out of your system.
