Found an interesting article of jellyfish stings:
The sting of a jellyfish has been shown to be one of the fastest processes in the whole of biology. Using a super-fast camera technique German researchers have found it can fire off in just 700 nanoseconds.
The team, writing in Current Biology, calculates that the acceleration is equivalent to 5,410,000 times gravity. Its impact generates a pressure of seven Gigapascals, which is in the same range as a gunshot.
