In Arctic Waters by Laura Crawford is an engaging 32-page picture book about northern mammals such as polar bears, walruses, seals, narwhals and beluga whales as they chase each other around "the ice that floats in the Arctic waters." Not only is the rhythmic, cumulative prose good for early readers; it is a pure delight to read aloud. The book is validated by the marine mammal specialist at the University of Alaska Sea Grant Marine Advisory Program. The final pages introduce an Inuk hunter into the rhyme. The colour illustrations give young readers the impression the mammals are happily chasing each other. Nevertheless background information provides teachers and adults with simple facts about these marine mammals found in Arctic waters.  Fountas & Pinnell: L
