Alatina alata, often called a sea wasp, is a species of box jellyfish found in the Pacific Ocean and Atlantic Ocean.


A. alata is a transparent box jellyfish with a bell height of 9 inches (230 mm). The species may lack nematocyst warts at least when young. The bell itself is transparent and very hyaline (glassy). Species of the Pacific (not including areas near Hawaii) are often very large, up to 12 inches (300 mm) long and up to 6 inches (150 mm) wide. Atlantic specimens vary in size from 5 inches (130 mm) long and 2 inches (51 mm) wide up to 10 inches (250 mm) long and 5 inches (130 mm) wide, occasionally larger. Some specimens have been seen with nematocyst warts. A. alata in Hawaii are about 6 inches (150 mm) long by 3 inches (76 mm) wide on average.


A. alata ranges across the Pacific and Atlantic and possibly the Indian Ocean. It is also found in the Arabian Sea along the beaches of Pakistan.[3]


Though the sting itself of A. alata is not particularly dangerous, it can cause a life-threatening reaction known as Irukandji syndrome. Unlike the true Irukandji, in which stings may barely be noticed at first, A. alata causes severe pain immediately following the sting. Symptoms start anywhere from within 5 to 120 minutes. Symptoms include headache, backache, muscle, chest, and abdominal pains, nausea, vomiting, sweating, anxiety, hypertension, tachycardia, and pulmonary edema.


Known for many years as Carybdea alata, it was given its current binomial name by Lisa-Ann Gershwin in 2005.[citation needed]

The diversity of each species may require more new species such as: Atlantic specimens (2 for with or without nematocyst warts), Indian Ocean species, several Pacific (not including Hawaii species) types, and an individual species for Hawaii.[clarification needed]
