Publisher's Synopsis
This work is intended to aid research into the diets of the many cetaceans, seals, fish and sea-birds that eat cephalopods. The book provides detailed instructions for collecting, preserving, transporting, examining, and identifying the lower "beaks" or mandibles of cephalopods belonging to almost all the known living genera. Many new illustrations, keys, descriptions and measurements make this a good reference work for zoologists who need to identify cephalopod remains from the stomachs of their predators. The illustrations include numerous line drawings and over two hundred stereo photographs.
