This document discusses the taxonomy, anatomy, adaptations, habitat, reproduction, and life cycle of whales. It notes that whales are mammals that belong to the order Cetacea, have thick layers of blubber for insulation, hindlimbs that are vestigial, and use horizontal tail flukes and echo location. The document focuses on the beluga whale species Delphinapterus leucas and its habitat in Arctic waters as well as general information on whale skeletons, sounds, gestation periods, and environmental concerns.
