Many people don't think much about the differences between a dolphin and a porpoise, but there are many. On the other hand there are several similarities. For example they are both mammals and both "dolphins and porpoises feed their babies milk" and "breathe air." Just at a glance you can see that the dolphin has a long pointed beak, but the porpoise's snout is more blunt and has a curve to it. If the porpoise decides to open its mouth you can see that it has sharp, pointed teeth. The dolphin doesn't have as many teeth as the porpoise and they tend to be flatter. Did you know that a killer whale, or orca, is part of the porpoise family? It is. That will give you an idea of how large members of the porpoise family can grow.
Neither of these animals are spectacular swimmers, but a "Dall's porpoise swims faster than the speediest dolphin. They both make good use of their flippers when they are swimming to propel themselves forward and steer clear from other porpoises and dolphins in a group. If you could peek beneath the water and compare the two, you'd find that the porpoise was not only shorter, but chunkier. In this book you'll also find out the difference between their fins, you'll learn about their blowholes, the fact that they swim in groups (pods), how many animals are in a pod, how they tend to their young, how they find food, and you'll learn many other interesting facts about both the dolphin and porpoise.
This book is an excellent science resource for children to learn about the differences between dolphins and porpoises. As a beginning science book, the print is large and is divided into four basic sections as it discusses the similarities and differences between the species. The photographs are plentiful and are very appealing. There are numerous informative captions that add additional information to the text. For example, when the description of the personality of the dolphin is described the caption reads: "People see porpoises less often than dolphins. Porpoises usually swim far from boats and people." In the back of the book is an index, a glossary, a photo/activity quiz to differentiate between the species, some Fun Facts, and additional recommended book and website resources to explore.
