Whales, Dolphins, and Porpoises: Of the Eastern North Pacific and Adjacent Arctic Waters, a Guide to Their Identification

This manual contains the technical information necessary for distinguishing similar species at sea. Numerous black-and-white photos show all important field characteristics. Detailed analysis of the field characteristics separating the various large Balaenopterids is especially useful. Species which have been recorded as accidental are also included. Updating information about the presence of Hyperoodon (or Indopacetus??) in Pacific waters near the equator would be useful, although photos of 'unidentified' Ziphidae are included. This is the only book I take out with me for field cruises.

This is an excellent book for those who are looking for a guide for whalewatching. But it is more technical than the average, which is good in some cases. FOr me it was very useful when going to sea, because I wanted detailed information, but other people look only for pictures. Which is the only problem here, because they are all in black and white.
