Illo es considerate le plus mortal medusa in le mundo que provoca le numerose incidentes resultante in injuria o morte del humanos.[2]
Le quantitate del veneno (toxina) de un animal es bastante pro occider 60 humanos adultes.[3]

C. fleckeri ha tentaculos de 3 metros de longitude que es coperite con milles de cnidocytos que, in contacto, lancea sagittas microscopic, alicun delivra un veneno de un poter extreme. Si le area de sagittas ([[aculeos) es significante, un victima non-tractate pote morir in 3 minutas.[3]
Chironex fleckeri es le plus grande del classe cubozoa (nominate communmente medusa-cubo), multe medusas de iste classe pote haber un veneno toxic similar. Ille campana cresce a le mesura de un balla de basketball, e ha 4 bochete de 15 tentaculos. Le color es blau palide, e es un creatura virtualmente transparente que es quasi impossibile de vider in le aqua, e un periculo pro le natatores.
Quando illo nata le tentaculos contrahe e ha le longitude de 15 cm e 5 mm in diametro; quando illes flutua, le tentaculos es magre e se extende a circa 3 metros de longitude. Le tentaculos es coperite con un concentration alte de cellulas con sagittas (o aculeos) nominate "cnidocytos".
Distribution e habitato
[modificar | modificar fonte]Le medusa es pelagic e ha essite documentate ab le costal aquas de Australia e Nove Guinea usque al le nord del Philippinas e Vietnam.[1]. Ma un proxime specie, Chironex yamaguchii (=Chiropsalmus quadrigatus) es describite in Japon in 2009 e confusion inter le duo species es possibile.[4]
