Silas, Nah. I used to spend entire days swimming among lightly stinging jellyfish on the New Jersey shore. Their sting was more itchy than painful. I'd swim until I got too itchy, then get out for a minute to rub dry sand on it, which took the sting away immediately, then go right back in the water. I actually loved it, because most people were too scared or grossed out to go in the water, so I had almost the whole beach to myself - with my own private life guards.
Mammatus clouds, also known as mamma or mammatocumulus, are pouches hanging from the base of clouds, usually cumulonimbus rainclouds. These clouds can also form with other types of clouds.
