It is all about location. The Maine Lobsters (clawed ones) are found in great numbers in the North Atlantic off the coast of the US. In the tropical waters off the south eastern coast of the US there are great numbers of Spiny Lobster and even Slipper Lobster. I can only tell you where I have seen them personally, I don't know about other parts of the world. I have never seen them in California, but I have only been diving there a few times. I did see a good number of them in Jamaica as well off Negril.
