A Study Of The Littoral Marine Isopod Crustacea Of The Dillon Beach Area, Robert James Menzies

University of the Pacific Theses and Dissertations

The primary purpose of this study was to provide accurate diagnoses of the littoral marine isopod crustacea in the Dillon Beach area. Such a purpose involved a much more complete study of the anatomy of the species represented in the fauna than was heretofore performed. Certain anatomical structures deemed by earlier writers as specifically diagnostic are demonstrated to be unreliable and in a great many instances other structures previously neither described or figured by American writers are considered of paramount importance in species identification. The number and magnitude of the changes proposed in this paper as illustrated in outline form …

Some Digenetic Trematodes From Deep-Water Fish Of Tortugas, Florida, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

Introduction (first two paragraphs)

The parasitic fauna of ocean depths is practically unknown. Although an extensive fish population occurs at all depths, very little study has yet been made on the helminths of these fish. During the summers of 1930, 1931, and 1932 excellent opportunity was offered for the collection of parasites from fish trawled from depths varying from 40 to 582 fathoms at Tortugas, Florida. A considerable number of systematic hauls by the staff and crew of the Tortugas Biological Laboratory of the Carnegie Institution of Washington yielded an abundance and considerable variety of fish, some of rare forms, …

A Morphological Study Of Daphniidae, Stanley E. Zawodny

Bachelors’ Theses

Th importance of fresh-water organisms is usually underestimated, especially by the very people who live near bodies of fresh-water and who thus can observe such organisms throughout the year. It is really easier to study minute life forms than it is to study larger organisms, for the former can be examined under all kinds of conditions as experiments are performed upon them. The purpose of this thesis is to give a short survey of the chief type among the fresh-water, Crustaceans, with special reference to morphology.

De Bestiis Marinis Or, The Beasts Of The Sea, Georg Wilhelm Steller

Zea E-Books in American Studies

Steller’s classic work, published in Latin in 1751 and in German in 1753, contains the only scientific description from life of the Steller’s sea cow (Hydrodamalis gigas), as well as the first scientific descriptions of the fur seal or “sea bear” (Callorhinus ursinus), Steller’s sea lion (Eumetopias jubatus), and the sea otter (Enhydra lutris).

Steller’s sea cow was a sirenian, or manatee, inhabiting the North Pacific Ocean and Bering Sea. It was first discovered by Europeans in 1741 and rendered extinct by 1768. It was a 30-foot long, plant-eating aquatic mammal, weighing …
