In the same collection that the previously reviewed Jurassic Giants, this book presents not only shark, but a variety of dinosaurs/prehistoric animals from the sea. A bit under the Jurassic Giants, because even if it presents some dinosaurs less knows by most people, it goes a bit less deep then the other one. We have some height/length comparison, but that about it, and mostly compare to the same big boat. Still a very interesting book, with gorgeous illustration, but I would have like it to goes with more comparison and more details on some of those big creatures.
