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

"Marine Protozoa from Woods Hole" by Gary N. Calkins is an early scientific work, revealing the microscopic world of marine protozoa near Woods Hole, Massachusetts. The text shares observations and descriptions of seventy-two delicate species, of these critical tiny creatures, vital to marine ecosystems. The book begins by addressing the limited knowledge of these tiny creatures in the US at the turn of the century, with a straightforward explanation of a study that spanned months, as one man sorted out many of the oceans tiniest organisms from only a small range. Calkins, through careful analysis, sheds light on the complexities to properly classify these organisms, comparing his discoveries to those previously identified in Europe. The book promises a journey into the detailed realm of marine protozoa which helps to highlight a careful process of gathering, watching, recording and organizing, setting the stage for understanding the unseen foundation of marine life.
