The Sea Wasp Jellyfish

Chironex Fleckeri

Kyondrah Pemental

Physical Features:

The Chironex Fleckeri which is more commonly known as the Sea Wasp Jellyfish has a very distinctive transparent bulb that is adorned by, on average 15 tentacles on each corner of the bell. Each tentacle is laced with millions of explosive cells called Cnidocytes that shoot out extremely venemous darts, once in contact with skin. Each tentacle can grow up to on average 9.8 ft long.Even cut off, the tentacles are said to still be able to inflict a venomous sting when wet. Each corner of the bulb also contains clusters of about 24 eyes, the eyes do not see like humans since they lack a central nervous system but studies have shown that they can indeed perceive different light rays.


This jellyfish most commonly inhabits the waters of northern Australia. There have been some sightings of this creature off the coasts of Guinea as well as Vietnam.

Human Impact:

The Chironex Fleckeri is said to be one of the most venemous creatures in the sea, the venom in its whole body being enough to kill roughly 60 adult humans. The sting untreated may end up killing the victim in two to five minutes. Once stung by this incredible creature the victim will experience excruciating pain where the tentacle came in contact with the skin, possible cardiac arrest, and impaired vision. The main cause of death found from the Chironex Fleckeri is a combination of respiratory failures and cardiac arrests that occur once the venom makes its way into the victim. Whip like marks can also be left on the victim.In the last 100 years there have been around 60 documented deaths caused by the Chironex Fleckeri, many of these victims being children and adolescents.


This Jellyfish may have a very powerful impact on humans once in contact, but their lifespan is less than a year. The oldest Chironex Jellyfish lasting around nine months in captivity. They die shortly after reproducing. Their clusters of eyes in each corner of the bell which perceive the different shades of colors help them move around by avoiding darker shapes and figures and moving towards lighter colors, as well as light perception they can sense vibrations in the water as well these skills help them avoid predators in the ocean and search for their next meal.
