Dolphins swim so fast it hurts (newscientist.com)

I knew that cavitation was a concern for submarines, pumps, ships, torpedoes, etc. It makes perfect sense that it could become an issue for any fast-swimming aquatic life as well.. but I don't think I ever put two and two together on that. (I guess I assumed no aquatic life could swim fast enough to have cavitation concerns)

Very interesting, but I think you meant to submit this to Reddit, not HN.

Sorry, could not find an article that provided more insight into details of cavitation and still has visual appeal.

If you really want to go into the cool technical stuff you should have a look at http://caltechbook.library.caltech.edu/1/4/bubble.htm
