Don't Google "Pearling"- posted from Hobe Sound, FL
Parents Beware: My son did a Google image search of "Pearling" for his presentation. We both learned something today...but it had nothing to do with diving for pearls. Very inappropriate results were found. Use the search term "Diving for Pearls" instead.
Videos are a good source of information about pearl diving as well- posted from Grove City, OH
If your student is youtube savvy, there are a number of good videos including this classic film (which is in Australia not mexico but that's OK). There are more, just search youtube for "pearl diving history mexico".
