Box Jellyfish

Here it is, the thing that is considered by most to be the deadliest living thing in the world (that isn’t a human). The Box Jellyfish is nearly invisible when you’re not looking directly at it, and it’s toxin can cause high blood pressure and death in a very short amount of time if not treated. If you ever find yourself stung by one, submerge the affected area in vinegar as you get yourself to a hospital ASAP!
