Carukiidae
Carukiidae is a family of box jellyfish within the Cubozoa class. Carukiidae can be easily classified by their lack of cirri clumps inside the cubozoan stomach, as well as the size and the placement of their nematocysts. Carukiidae use nematocysts as a defense mechanism; they releases a venom from the tips of their nematocysts, producing the Irukandji syndrome. Even though positions of spines on the shaft of the Carukiidae cause illness, there are areas on the body that do not. The rhopalial niche openings, which discern light, do not incur any illness. The Carukiidae also have non-venomous rhopaliar horns, which are imperceptive in function and located above the rhopalial niches. Irukandji syndrome triggered by Carukiidae requires immediate medical attention. In the event that it goes untreated in humans, cardiac arrest is a potentially deadly consequence.

Morbakka Virulenta
''Morbakka virulenta'' is a species of box jellyfish that is found in waters near the islands of Japan. The species was originally described in the genus '' Tamoya'' by Kamakichi Kishinouye in 1910. However, unlike other species of that genus, this jellyfish did not have the vertical gastric phacellae which protect the inside of the bell with nematocyst warts. As a result, it was reclassified to the genus ''Morbakka'' due to its distinctively shaped rhopaliar horns which resemble rabbit ears. Because of its painful stings, ''M. virulenta'' has been nicknamed ''Hikurage'', which is “fire jellyfish” in Japanese.''Bentlage, Bastian; Lewis, Cheryl (2012).

It was first described to science in 2012, and is one of four species in genus ''Malo'', often confused in the past with the '' M. maxima''. Description ''M. filipina'' is a small Carybdeida, measuring between 30 and 40 mm.

Malo Maxima
''Malo maxima'' is a small, and extremely dangerous Irukandji Jellyfish that is known to cause Irukandji Syndrome. It is one of the four species of ''Malo'', along with ''Malo bella'', ''Malo filipina'', and ''Malo kingi''. The ''Malo maxima'' was first described in 2005 by Lisa-ann Gershwin, who also described the Malo bella and ''Malo kingi'' jellyfish along with over 200 other species of jellyfish. ''Malo maxima'' differs from other species of jellyfish in many ways but the most confusing one is that they swim more like fish than jellyfish, however the reason for this is still unknown. Phylogeny The ''Malo maxima'' has a tall, narrow, robust body with a flattened apex and measures to about 5 cm. Even though it is very small, ''Malo maxima'' is the largest of the Malo genus. They are also translucent, making them very difficult for the human eye to see easily. Research from the scientific paper “Early Life History and Metamorphosis in Malo maxima” showed that the met ...

Morbakka Fenneri
''Morbakka fenneri'', also known as the Moreton Bay stinger or the fire jelly, is a small box jellyfish found in the waters of Australia and Thailand. It has a transparent bell shape with four mauve colored tentacles that are each 50cm long. It is hard to capture this jellyfish to study it due to its small size, fragility, toxicity, and similarity to other species of box jellyfish. The sting from this species results in symptoms similar to Irukandji syndrome Irukandji syndrome is a condition that results from envenomation by certain box jellyfish. In rare instances the sting may result in cardiac arrest and death. The most common jellyfish involved is the ''Carukia barnesi'', a species of Irukandji .... The wound is typically 10mm wide and is followed by an immediate burning sensation. If left untreated, it can become necrose, pruritic, and vesicule.

Box Jellyfish
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their box-like (i.e. cube-shaped) body. Some species of box jellyfish produce potent venom delivered by contact with their tentacles. Stings from some species, including ''Chironex fleckeri'', ''Carukia barnesi'', ''Malo kingi'', and a few others, are extremely painful and often fatal to humans. Taxonomy and systematics At least 51 species of box jellyfish were known as of 2018. These are grouped into two orders and eight families. A few new species have since been described, and it is likely that additional undescribed species remain. Cubozoa represents the smallest cnidarian class with approximately 50 species.

Carukia Shinju
''Carukia shinju'' is a small and venomous jellyfish found off the waters of northwestern Australia. Specifically, located offshore of the coasts of Australian states including Queensland, The Northern Territory, Western Australia and South Australia. Stings can result in Irukandji syndrome Irukandji syndrome is a condition that results from envenomation by certain box jellyfish. In rare instances the sting may result in cardiac arrest and death. The most common jellyfish involved is the ''Carukia barnesi'', a species of Irukandji .... The mechanisms of actions of their toxins are not completely understood, but evidence shows they include modulation of neuronal sodium channels leading to large releases of endogenous catecholamines that can lead to possible stress-induced cardiomyopathy.
