Jellyfish swell into the beach in large numbers not uncommon in Hawaii. The famous box jellyfish possesses powerful venom that can instantly paralyze or kill prey like fish and shrimp, according to National Geographic. The venom of some of the world's most powerful jellyfish species. Their sting can be extremely painful for humans, sometimes leading to death. However, a few other species of jellyfish are not a serious threat to humans. Three species of box jellyfish can be found in the waters off Hawaii that have less venom than their relatives.

Jellyfish appear year round in the Hawaiian sea. But they often rush to the south of O'ahu Island, causing the beach to be closed temporarily for 8 - 10 days after the full moon, according to Hawaii Aloha Travel. This is due to their mating habits associated with tidal conditions and moon phases. Strong winds can also blow large quantities of jellyfish toward the coast.

Similar to other venomous jellyfish, the box jellyfish tentacle is covered with thousands of microscopic spiny burning cells that can pierce the skin. According to research by a group of scientists at the University of Hawaii, Mānoa, many first-aid instructions for burning box jellyfish, including washing with seawater, only make matters worse. According to them, the most effective way to treat the sting is to wash the area exposed to poisonous jellyfish with vinegar and remove tentacles with tweezers, then apply a thermal pad to reduce the level of venom.
