Summary "Pearls & Parasites" by Sir A. E. Shipley is a scientific publication written in the early 20th century. The collection consists of essays that delve into topics in zoology, focusing on the formation of pearls, the life cycles of molluscs, and the impact of parasites on these processes. The book aims to bridge traditional beliefs about pearls and the biological realities revealed through scientific inquiry. The opening of "Pearls & Parasites" sets the stage by exploring ancient beliefs surrounding the formation of pearls and contrasts these myths with scientific understanding. Shipley discusses the complex biological processes that lead to pearl formation, emphasizing the role of parasites as nuisances that compel oysters to create pearls as a defense mechanism. He details the anatomy of the oyster shell and the layers involved in the production of nacre, illustrating how foreign bodies trigger this process. This introduction not only piques interest in the biological mechanisms involved but also hints at the intertwined relationship between beauty (pearls) and survival (parasite defense) within marine life.
