Finding cannonball jellyfish washed up on the shore at Myrtle Beach seems to be the norm every time we visit there.... so why does this seem to be such a common occurance? Well, they experience a tidal upwelling at high tide. This typically occurs 8-10 days after a full moon. These ocean drifters are at the mercy of the currents and with some regularity, they make their way to the shore and get stuck, sadly, to their demise.
According to the South Carolina Department of Natural Resources, cannonball jellies are the most common jellyfish in the area and fortunately, for locals and vacationers alike, they are one of the least venemous. Fun fact: They have no tenticles!
Fishermen consider them a nuisance because they clog up their fishing nets. Kids walking on the beach are fascinated by them and you'll occasionally see a really brave one touch them on top of their head. Its all part of the Myrtle Beach experience.
