Black-and-white skin glistens ... Blowhole puffs ... Meet the orca, also
known as the killer whale! Brimming with vivid photos and scientific
facts, Orcas treats middle-grade researchers and wild animal lovers to a
comprehensive profile of this marvelous marine mammal. It covers zoology
topics such as anatomy, diet, ocean habitat, and life cycle, as well as
species conservation efforts and the animal's relationship with humans
throughout history. Sidebars, a range map, and a glossary support the
main text, while an orca tale from the Tlingit people of Canada adds a
cross-curricular cultural layer to the title.
