Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901

A quiet summer at the historic Woods Hole laboratory becomes a vivid journey into an unseen world. Over the course of two months the author collected algae‑laden water from a modest wharf and, through patient observation, identified seventy‑two distinct protozoan species. The narrative walks listeners through the simple tools and methods of the era—fresh samples, standing jars, and careful microscopy—while unveiling a surprising diversity thriving on a few square meters of shoreline.

Beyond the inventory, the work offers a thoughtful discussion of how these microscopic inhabitants fit into broader ecological and economic contexts, especially for fisheries. By extending classic European descriptions rather than proliferating new names, the author presents a measured, accessible taxonomy that highlights groups such as infusoria, flagellates, and the occasional deep‑sea foraminifer. Listeners will come away with a clear picture of early‑20th‑century marine biology and a renewed appreciation for the tiny organisms that underpin ocean life.
