Do jelly fish sting each other?
Stingin cells are activated only if the jellyfish touch and recognize some specific organic compounds; in this way, they don’t stingthemselves, other jellyfishes of the same species (and probably some similar ones), while can recognize and sting some other cnidarians; however, is possible that the nervous system, in some cases, can choose, indipendently form the specific stinging cell receptions, if to sting or not.
