Sorry-people don't make a habit of wearing diving suits while playing in the sand ob the shore & running 3 feet into the ocean. The sting of the Portuguese man-of-war is more painful than that of the common jellyfish. Some people have described a sting from the Portuguese man-of-war as a feeling like being struck by a lightning bolt, and this sting has been responsible for two deaths. The Portuguese man-of-war is a large invertebrate whose tentacles can reach up to 100 feet in length. Even detached tentacles of these animals are capable of causing stings to humans for up to two weeks. Stings from box jellyfish (cubozoans) are the most dangerous type of jellyfish sting. The box jellyfish found in Australian waters has venom so deadly that it may cause cardiovascular collapse along with respiratory and neuromuscular paralysis that can kill an adult within minutes. Poisonings by the box jellyfish of Australia require the administration of an antivenom, which reverses the effect of the poison.
