Jellyfish in Hawaii

Jellyfish are present in almost all the waters of the world. The islands of Hawaii, being surrounded by water witness sightings of a number of species of jellyfish. Residents of Hawaii as well as visitors get to see huge swarms of jellyfish, sometimes a billion strong, in the waters around the islands of Hawaii.

Of all the jellyfish that are found in the waters around Hawaii, the box jellyfish is one of the most prolific as well as the most dangerous. The jellyfish is so called because of its box like shape. The box jellyfish found in Hawaii is about 1-3 inches in diameter and has tentacles that can grow up to 2 feet in length.

The box jellyfish in Hawaii is closely related to the one found in Australia. The Australian box jellyfish, Chironex Fleckeri, is one of the most deadly animals in the world. Its venom is so powerful that it can kill up to 60 human beings in a matter of 3-4 seconds. However, the box jellyfish in Hawaii, Carybdea alata and Carybdea rastonii, are not as dangerous as their Australian counterparts. The sting of the box jellyfish in Hawaii can be very painful and may leave a very inflamed rash, and may cause anaphylactic shock in some sensitive individuals, but are unlikely to cause death. In any case, immediate medical attention is required.

The behavior of the box jellyfish in Hawaii is extremely predictable and is very useful in avoiding jellyfish related incidents. Every month, between 8 to 12 days after a full moon, the box jellyfish in Hawaii tend to swarm near the shores. At this time, swimming in the jellyfish infested water may not be advisable. The swarms are typically found on the west and south shores of the islands. The main purpose of this swarm is to spawn and the few days after a full moon seem to provide perfect conditions for the mating ritual of the box jellyfish in Hawaii.

If you are considering stepping into the sea waters around Hawaii, it would be prudent to first ensure that the water is free of any dangerous jellyfish. The best way to find out if the ocean is infested with jellyfish is to inspect the shoreline. Jellyfish have extremely low body mass, and they tend to get carried away by winds at the surface of the water or by the water's tides and currents. If there are any swarms of jellyfish near the beach, some of them are bound to have washed up on the shore. Inspect the shoreline to ensure that large numbers of jellyfish are not deposited on the beach.

The other important precautions to take include reading all relevant public notices and signs that are posted around the beaches of Hawaii. Also, talk to the local lifeguards and ensure that the waters are safe to swim in. Finally, ensure that you have a jellyfish first aid kit handy, in case of any emergency. Also, ensure that medical help can be easily and quickly accessible from where you are in Hawaii.
