Chironex fleckeri, commonly known as the sea wasp, is a species of extremely venomous box jellyfish found in coastal waters from northern Australia and New Guinea to Malaysia, the Philippines and Vietnam. During a series of tests by marine biologists including Australian jellyfish expert Jamie Seymour, a single jellyfish was put in a tank. Researchers at the University of Hawaii's Department of Tropical Medicine have found that the venom causes cells to become porous enough to allow potassium leakage, causing hyperkalemia which can lead to cardiovascular collapse and death as quickly as within two to five minutes with an LD50 of 0.04 mg/kg, making it the most venomous jellyfish in the world (to laboratory mice). The box jellyfish Chironex fleckeri produces extremely potent and rapid-acting venom that is harmful to humans and lethal to prey. Learn about this topic in these articles: cubozoan medusae. [1] To further confuse, the closely related and also dangerously venomous Chironex yamaguchii was first described from Japan in 2009. The name Chironex fleckeri is the combination of greek and Latin words. Chironex Fleckeri. 3078 ). Since it is virtually transparent, the creature is nearly impossible to see in its habitat, posing particular danger to swimmers. Chironex fleckeri is a large box jellyfish commonly found in Australia waters, and suspected through out the Indo Pacific region (Fenner and Williamson, 1996, Gershwin et al., 2010, Tibballs, 2006, Lippmann et al., 2011).

Using sheep erythrocyte haemolysis as an indicator of cytolytic activity, two major cytolysins, with native molecular masses of ∼370 and 145 kDa, and one minor cytolysin (∼70 kDa) were isolated. A doctor named Hugo Flecker suggested the name chironex fleckeri for this species of box jellyfish. The polyp is tiny and inconspicuous. Chironex fleckeri is a dangerous Australasian box jellyfish that inflicts painful, debilitating and potentially life-threatening stings in humans. Chironex fleckeri is a box jellyfish. It is commonly found in the coastal waters from New Guinea to Malaysia and northern Australia. [3] The amount of venom in one animal is said to be enough to kill 60 adult humans, Cnidaria Envenomation. I've been contacted by a marine biologist called Bastian Bentlage who co-wrote a paper on Japanese box jellies and this little guy (the bell is about one inch/3cm wide) is quite probably a specimen of a recently discovered subspecies of Chironex called yamaguchii. In cnidarian: Size range and diversity of structure …Asia, and include the so-called sea wasps. It is a large jellyfish, weighing up to 13 pounds and measuring about 7" to 11" across the dome while the tentacles can droop about 6' from the base. [4] Most deaths in recent decades have been children, as their smaller body mass puts them at a higher risk of fatal envenomation. This also gave further relief of pain.

Venom proteins from the nematocysts of Chironex fleckeri were fractionated by size-exclusion and cation-exchange chromatography. Using sheep erythrocyte haemolysis as an indicator of cytolytic activity, two major cytolysins, with native molecular masses of 370 and 145 kDa, and one minor cytolysin (70 kDa) were isolated. Most species of jellies are saucer shaped, but the box is square shaped. Here, we describe the characterization of two C. fleckeri venom proteins, CfTX-A (∼40 kDa) and CfTX-B (∼42 kDa), which were isolated from C. fleckeri venom using size exclusion chromatography and cation exchange chromatography.

It produces potent and rapid-acting venom and its sting causes severe localized and systemic effects that are potentially life-threatening. [16] A 2014 study demonstrated in vitro that while vinegar deactivates unfired nematocysts, there was also an increase in venom concentration in the solution, possibly by causing already-fired nematocysts (which still contain some venom) to release what remained. Chironex fleckeri lives on a diet of prawns and small fish, and are prey to turtles, whose thick skin is impenetrable to the cnidocytes of the jellyfish.

Also, the researchers did not determine whether the increase in venom concentration was caused by already-discharged nematocysts releasing more venom, or if the venom that was released initially had simply leaked back out through the membrane, thus confounding the concentration measurement. On average, however, the animals are much smaller, being more typically 60 millimetres (2.4 in) in height. Chironex fleckeri (Box Jellyfish) from £4.50. The adult can be up to 10 feet long, and it can weigh over 4 pounds.
