Havsgetingen – giftigaste maneten

Most often, these fatal envenomations are perpetrated by the largest species of box jelly, Chironex fleckeri, owing to its high concentration of nematocysts, though at least two deaths in Australia have been attributed to the thumbnail-sized irukandji jellyfish (Carukia barnesi). Those who fall victim to Carukia barnesi suffer several severe symptoms known as Irukandji syndrome. The box jellyfish actively hunts its prey, rather than drifting as do true jellyfish. It is capable of achieving speeds of up to 3.5 knots (1.8 m/s).<p style="margin-top: 0.4em; margin-right: 0px; margin-bottom: 0.5em; margin-left: 0px; line-height: 1.5em;">The venom of cubozoans is very distinct from that of scyphozoans, and is used to catch prey (fish and small invertebrates) and for defense from predators.
