This cute little fella is called a blue-ringed octopus. While it looks pretty, it carries a deadly bite. No antivenom is available, and many people are unaware they have been bitten until symptoms emerge.

have a look at the palm of your hand. Thats how big this blighter is. the whole octopus fits in there.



In the second picture you can barely make out the beak

The only attack you if they feel threated, but as nobody has done a psychological profile of octopi we don't know what makes them feel threated... things like only having 2 legs or being hairy
