Through the use of their very sharp spine and venom, plus camouflage and nerves that sense the electrical fields of prey, stingrays are excellent survivors in the wild.  Being ovoviviparous, their young hatch from eggs inside the mother, then are born live and self sufficient.  Having first developed around 200 million years ago, stingrays have close relatives in the sea world.  Stingrays live close to shore and thus are heavily  affected by human pollutants.  These topics and more fun facts are covered in this amazingly informative text, which is also full of equisite photos.  Front Matter includes a fact file list of Class, Order, Families, Genus, Species, World Distribution, Habitats, Distinctive Physical characteristics, Habits, and Diet…helpful to elementary researchers.  Back Matter includes, Glossary, Habitat Map, Find Out More, Index and About the Author.  If all of the books in this Nature’s Children series are this quality, I’m going to be purchasing others.
