The Blue Ringed Octopus

The blue ringed octopus is a small octopus that has a palish body and blue rings. This is the only octopus who's venom is deadly to humans. It's venoms major neurotoxin component is the same as pufferfish and some poison dart frogs. It's venom can result in nausea, respiratory arrest, heart failure, severe and sometimes total paralysis, and blindness. It can cause death in minutes if not treated. First aid treatment is pressure to the wound and artificial respiration once the paralysis has disabled the victim's respiratory muscles, which often occurs within minutes of being bitten.Because the venom primarily kills through paralysis, victims are frequently saved if artificial respiration is started and maintained before marked cyanosis and hypotension develop. Victims who survive the first 24 hours usually recover completely. This octopus had a part in the 007 movie Octopussy.
