A killer of many names and is still lethal to mankind since its sting is deadly. This sea creature, are usually found in Australian waters. It is sometimes called as sea wasp, boxfish, fire medusa, or just a killer stinger.
The lethal type is the biggest or the largest of the box jellyfish species and it is the Chironex Fleckeri. It grows to a respectable size at about 20 cm along each side (the box side)and its tentacles grows to about 3 meters long. Usually it would weigh up to 2 kg. This lethal killers feast on small fishes and other crustaceans. They use their stinging mechanism to kill their prey before feasting on them. A swimmer sometimes may not notice this killer because it is transparent and pale blue in color. This makes them invisible in the waters. There are no reports as to when would this box jellyfish be in season and are present in rivers. They are just there waiting for their next victim.
Now, we will talk about it’s deadly weapon, it’s venom. This jellyfish has thousands of stinging cells or what we call it nematocytes. It has this cells in each of its tentacles. This deadly venom can stop ones heart in minutes or one may experience cardiac arrest once it has been stung. The victim usually starts on feeling severe and unbearable pain on the part where the tentacles have touched and usually will experience difficulty in breathing.
To all who likes swimming in tropical rivers, always be on a lookout for jellyfishes, whether it is a box jellyfish or not. Always bring with you a vinegar. Vinegar’s acid helps stop the nematocytes from loading the venom to the victim’s skin. Wash of the tentacles that is clinging to the skin with vinegar and soak it for 30 seconds. Expect scars on the skin caused by the clinging of the jellyfish’s tentacles since it has been necrotized by the venom from its tentacles. For some instances that if one has been stung by a normal jellyfish, ice can be used as first aid to the stung part of the skin or one can take in painkillers and antihistamines.
Getting stung by a box jellyfish shows an 80% of survival. There are 63 people reported who died in Australia since 1884. This is crucial. Always be on guard when swimming in rivers and shallow waters.
