Maidenhead: WILDGuides, 2001. Octavo, paperback, illustrations, maps.

This is an excellent practical, pocket-sized photographic guide to the 27 species of cetaceans that are known to have occurred in European waters (excluding the far north). Based on experiences gained by regularly travelling the ferry runs across the channel and Biscay, the authors have produced a very useful review of the field id of cetaceans at sea, backed up by a comprehensive set of colour photographs and line drawings.
