See text Malo is one of a genus of box jellies in the family Carybdeida in the Phylum Cnidaria.

The name Malo is derived by the first two letters of the name of Mark Longhurst, who survived a severe sting by a jellyfish apparently from the genus shortly before the publication of its discovery.

The author, Gershwin, also noted the "interesting coincidence that the word “malo” is Spanish for “bad”, as this species is presumed to be capable of lethal envenomation.

Irukandji stings are the highest occupational safety hazard for Marine industries in Australia and the Indo-Pacific Ocean.

Symptoms include: muscle cramps, vomiting, sweating, agitation, vasoconstriction, prostration, hypertension, and severe envenomation, and acute heart failure.

[2][4] The toxins induce modulation of neuronal sodium channels leading to massive release of endogenous catecholamine (dopamine, epinephrine, and norepinephrine) and stress-induced cardiomyopathy.

For clinical treatment pain is managed with various analgesic and medication to prevent cardiac failure in severe cases.

[2] Reports of other possible locations of the Malo genus of Jellies have been in Hawaii, Florida, Papua New Guinea, French West Indies, Bon Air, and Caribbean.

The technique uses species-specific DNA identifiers in collected samples to gain insight on rare and mysterious animals.

[7][8][9] The Malo genus of jellies are incredibly small and translucent making identification hard.

Malo contain a frown shaped rhopalial niche openings where they are undivided on the upper and lower covering.

The species Malo kingi has mammillation which are a collection of stinging cells on the apex and walls of the bell.
