Hawai‘i County Civil Defense said Thursday afternoon that the state Department of Land and Natural Resources reports box jellyfish at Spencer Beach Park in South Kohala and at other West Hawai‘i beaches.

Box jellyfish are small and nearly colorless making them difficult to see. Seven to 10 days following a full moon, which last occurred Jan. 17, box jellyfish come close to shore and can pose a possible hazard, according to Civil Defense.

Box jellyfish venom is poisonous. In extreme cases, the venom can cause paralysis, cardiac arrest and even death.

Civil Defense advises beachgoers, swimmers and surfers to:

  • Exercise caution and heed all instructions given by ocean safety officials and beach park staff.
  • Avoid entering the water where box jellyfish are present.
  • Keep vinegar in your first-aid kit and available.

According to county spokesperson Cyrus Johnasen, no beach closures are planned at this time. The county is monitoring the situation and cleaning up jellyfish accordingly as they wash ashore.
