Jellyfish are known to be gentle creatures, and in most cases pose little threat to People. However some jellyfish have the ability to cause severe pain and even kill humans, depending on the jellyfish. I had always loved sea life, and found jellyfish interesting. It was not until I was eight that I actually got to see a real jellyfish in San Diego. I was walking along the beach and saw it upturned in the sand, being a curious lad I immediately wanted to touch it. This ended up getting me my first sting, which was obviously not too severe but still very painful. And from then on I always wondered how a fish made of almost entirely water could cause such pain, and then I realized it must be chemistry

All these components of jellyfish venom form naturally in its body.While the main purpose of the toxins is too cause pain the main component of the venom is Porin. Composed of strands of amino acids they form a shape that can breach cell membranes releasing chemicals in the blood such as potassium. Now this potassium is what actually kills, because once the heart pumps in too much potassium from the blood, you go into cardiac arrest. Because this Potassium floods the nerves and the body can no longer send signals and in the heart muscle this causes heart rate to become out of rhythm, causing cardiac arrest.
