Cover photographs: The first known Irukandji jellyfish, Carukia barnesi, periodically infests North Queensland beaches and reefs. Its sting produces life-threatening illness in its victims (© Lisa Gershwin). The presence of Irukandji jellyfish often leads to beach closures in North Queensland (© Scott Condie).
