Paperback. Zustand: New. Print on Demand. This book explores the diverse world of nemerteans, soft-bodied worms found in marine environments, and their unique characteristics. The author meticulously describes 57 species of nemerteans from the Pacific coast of North America, including seven not previously recorded in the region. Comparing these species to their European counterparts, the author sheds light on the remarkable similarity between the nemertean faunas of the Pacific coast and those of Europe and the Mediterranean Sea. The book provides valuable insights into the distribution, anatomy, and evolutionary relationships of nemerteans, highlighting the abundance and diversity of these fascinating creatures in this coastal region.

Taschenbuch. Zustand: Neu. Neuware - This biographical memoir provides a comprehensive look into the life and scientific legacy of Sidney Irving Smith (1843-1926), a distinguished American zoologist and a professor of comparative anatomy at Yale University.
