This book is a handbook for students that offers concise information on digenetic trematodes and cestodes that infect domestic and wild animals. It is useful particularly for undergraduates in the fields who have taken or are currently taking Parasitology or Zoology course, and for the general audience who have interests in Parasitology. It is not intended to be a comprehensive textbook in the field of Parasitology. It is hoped that this text will be helpful to understand the outline of the parasites and their diseases.
