Well, this book has many different types of marine life. Everything from sea lions to sea horses, but many of the patterns are unattractive, really. They are sized for immediate use, which is refreshing becasue so many pattern books give you itty bitty patterns and they you have to run to the copy shop, so that is one plus. But if you are looking for cool tropical fish scenes like I was, this is not the book for you. Too many boring and bland patterns of strang looking star fish and sharks, and many other peculiar animals which just don't translate well to glass.
