Polar bears have supersharp, curved claws that can be 2 inches long. Polar bears use their claws to grip the ice they live on as well as for hunting their main prey, the seal. In this dynamic book, readers investigate polar bears' bodies, from jaws to claws! Full-color photographs bring readers closer to a top predator than they could ever get in the wild or even the zoo. The main content supports knowledge building, a key component of the science of reading.
