Endangered Marine Life

Paper Summary:

The purpose of this research paper is to provide an analysis of the pseudorca crassidens, phocoenoides dalli, and Cephalorhynchus eutropia. Information about the phylum, class, order, family and genus, as well as background information and the effects of human interaction are provided for each species. Because the effects of pollution are similar for all three species and marine life in general, the paper closes by providing a section dedicated to pollution and its effects on these species, marine life in general and human beings.

From the Paper:

"Pseudorca crassidens are not a species of dolphin that humans tend to hunt for commercial purposes, thus they live is slightly less influenced by human interaction than other species. However, many are caught as "bycatch" most commonly in places that allows "long-line fishing" (MarineBio.org, 2007). Some believe however, despite the fact that these dolphins or marine mammals are not hunted specifically, may be "genetically extinct, with less than 80 or so species found off the coast of Hawaii" where these mammals typically swim and linger (MarineBio.org, 2007). Because of the lack of genetic diversity there is some risk for mutations, which ultimately will lead to their demise. At this point there is little humans can do to correct past wrongs to remedy this situation. "
