Great Barrier Reef 1500 + 400

I found a very interesting puzzle, it is heart island in the Great Barrier Reef. The image is awesome but the format is very interesting. It is a1500 piece puzzle with a bonus 400 piece mini puzzle of a portion of the larger picture.

This is an example of the 1500 + 400 puzzle. It is two puzzles in one, a 1500pc and a 400pc of the smaller section of the same image... love it!
