Did you know that octopi are as smart as dogs? Or that Viperfish have 350 lights in their mouths? You'll find these and more interesting facts in SEA MONSTERS, the companion research guide to DARK DAY IN THE DEEP SEA. Discover old sea monster legends, info on squids, octopi, and other animals in the abyss. Also learn about prehistoric sea monsters, and exploration of the deep sea. I've met the Scientific Consultant for this book, Dr. Sonke Johnsen, he said that "The world will need thousands of new Marine Biologists, because we've only just begun to explore the mysteries of the deep sea." I'd highly recommend this book to all fans of the MAGIC TREE HOUSE series, especially kids ages 7-12, who are interested in Deep Sea animals.
