This handbook investigates the biological characteristics and behavioral patterns of whale species while providing a practical framework for identifying and observing them in their natural habitats. Eric Hoyt, a recognized authority on marine mammals and conservation, synthesizes decades of field research and observational data to create a comprehensive guide for both amateur enthusiasts and serious naturalists. The text argues that informed observation is a critical component of whale conservation and public engagement with marine ecosystems.

Experts and naturalists frequently cite this work as a foundational reference for those interested in marine mammal tourism and field identification. Readers often note the accessibility of the prose, which balances scientific accuracy with practical utility for the casual observer.
