Please note that 'Clipperton Island,' a French possession located in the Eastern Pacific Ocean (1630 miles south-southeast of San Diego, California) is named for "John Clipperton" an English buccaneer who led a mutiny against its founder William Dampier in 1708. This reader is an ancestor of John Clipperton and named after him. And of course, Clipperton Island is the home of the rarely collected Holacanthus limbaughi, the Clipperton Angelfish.
I want to thank John for his nice comments about my website and his devotion to the hobby. If you visit his website at pbase.com you'll see several of his aquariums and the beginnings of photo libraries dedicated to various wildlife. - Bob
