The Portuguese man-of-war is a brilliant blue-purple hydrozoan that has long tentacles capable of stinging victims with a whiplash-like pattern. The stings typically cause wheals that occur in stripes. The characteristic sting is not caused by whips from the tentacles but from irritants that the tentacles deposit on the skin of the victims.
