There are at least 22 species of sharks in Monterey Bay, the fugure of '200' is a typographical error.
As well, there were some other small inaccuracies in detail (re sharks) but over all its very fortunate that noone was injured; moreover one cannot have a better explanation for a broken surfboard. Like the old saying, 'come back with this board or upon it', and so it goes. Cheers, Sean Pelagic Shark Research Foundation
