Blue- ringed Octopus

The unique, blue- ringed pattern all over its body entrances an observer, but this delightful- looking animal is quite dangerous, given that a bite from its parrot- like beak can introduce tetrodotoxin to the victim’s system. Tetrodoxin: 1,200 times more poisonous than cyanide, can be deadly if not treated immediately. First aid: While on the way to the hospital, apply pressure through a tourniquet to keep the toxin from spreading throughout the body, removing the bandage every 90 seconds then reapplying it again for 10 minutes.
