You may not see a Portuguese man-of-war when you re swimming in the ocean. Yet that doesn t mean you re safe. A man-of-war s tentacles are so long up to 165 feet (50 m) that a swimmer could brush against them and get stung without ever seeing the creature. A sting from the man-of-war is extremely painful, but fortunately it usually isn t strong enough to kill a human. In Portuguese Man-of-War: Floating Misery, kids will learn all about the natural habitat, physical characteristics, diet, and behavior of this dangerous sea creature. Spectacular, full-color photos and a narrative format will keep readers turning the pages for more.
