IPBiz had recently written about tetrodotoxin, produced by bacteria on pufferfish. In a recent hierarchy of the deadliest poisons, tetrodotoxin/pufferfish ranked number 10, to the number one of the irukandji jelly fish.
If the irukandji jelly fish sounds familiar, it should, because it was a plot element on the episode of CSI New York titled Buzzkill. Of relevance to inventors, in that episode, the victim of an idea theft planted the Irukandji Jellyfish in a beach ball intended for use by the idea stealer. Killed the wrong person though. In a different episode of CSI New York ("Death House"), a ripped off inventor did kill the idea stealer. Is CSI New York promoting a Hobbsian alternative to patent infringement lawsuits?
In passing, if being a target for an irukandji is not on your list of job objectives, see 10 Jobs That Will Get a Raise in 2010.
