The world can be a weird place. Scientists teach mice how to drive tiny cars. People build upside-down houses. And fish in the deepest, darkest parts of the ocean lure prey using glowing bulbs that hang from their heads. Weird World uncovers these and other bizarre cases in a variety of subjects including sports, animals, and history. Aligned to Common Core Standards and correlated to state standards. Core Library is an imprint of Abdo Publishing, a division of ABDO.
