Life of Sea | Sea Wasp (Chironex flecker) | Sea wasp or Box Jellyfish or Box Fish is the most poisonous sea creature than stone fish, sharks or sea snakes. Even it is a beautiful jelly, it has slain more people than other marine animals. Box jellyfish are usually found in shallow water. If you see the Box jellyfish to the sea, you are not allowed to water activities to do. They live in the coastal waters of northern Australia and New Guinea to the north to the Philippines and Vietnam. Scientific classification
Class: Cubozoa, Werner, 1975
The Box jellyfish has a large transparent bubble or cube as the body and is divided into segments. They have a transparent body with a light blue color. It has stinging tentacles. Each tentacle of a jellyfish box can store up to 5,000 of these nematocysts. The Box jellyfish uses these tentacles to catch its prey, such as small fish and crustaceans. Box jellyfish is, unlike many other jellyfish, equipped with four eyes. Eyes are connected to a nerve ring and the creature can take evasive action or move to his prey. Two of the eyes in the set to detect only light. It has no brain, no heart and no blood.
Box jellyfish feed on small crustaceans and small fish. These animals have a strategy to capture their prey. They will wait for prey to bump into their tentacles. They will then slain by their stinging tentacles to poison Stong. However, turtles are not affected by stabbing them. Sea turtles lay their predator. Box jellyfish is responsible for more deaths than in Australian snakes, sharks and saltwater crocodiles. Box jellyfish are known for the highly potent poison produced by a number of species: Chironex fleckeri, Carukia barnesi and Malo Kingi are among the most poisonous animals in the world. Stings from these and some other species in the class are very painful and sometimes fatal to humans. In most cases, the sting of the Box jellyfish do not cause death, but it always has the potential to do so. In fact, the jellyfish, the most toxic, releases a small amount of poison that it rarely causes death. However, each stitch is extremely painful and requires immediate medical attention. In the worst cases of stabbing, anti-poison can be applied.
The poison of the Box jellyfish has cardiotoxic, neurotoxic and highly dermatonecrotic components. When injected, it is quickly absorbed into the circulation. The pain is unbearable, the tentacles are sticky and adhere tightly to the skin. Any attempt to remove the tentacles while they are still active may worsen the sting and cause major injuries. Severe stabbing result in necrosis of the affected skin. If treatment is not given, the pain may take weeks and often leave significant scars stabbing.
Domestic vinegar (never methylated spirits) to be poured over the tentacles stick to inactivate nematocysts as soon as possible. If the tentacles are inactive, they can be safely removed. (The use of vinegar is not intended to reduce pain or to reduce effects of the poison, it will only stop further discharge of nematocysts). In case of respiratory or cardiovascular collapse, basic life support, such as artificial respiration and CPR required. Where antivenom is not available, the pressure-immobilisation of limbs after inactivation of nematocysts are used while the patient is transported to the hospital.
