Nylon Shell
Chapter I
INTRODUCTION
Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world. At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms contribute significantly to the oxygen cycle, and are involved in the regulation of the Earth's climate. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. Many species are economically important to humans, including Nylon Shells (Phapia undulata). It is also becoming understood that the well-being of marine organisms and other organisms are linked in very fundamental ways. The human body of knowledge regarding the relationship between life in the sea and important cycles is rapidly growing, with new discoveries being made nearly every day. Bivalves have a shell consisting of two asymmetrically rounded halves called valves that are mirror images of each other, joined at one edge by a flexible ligament called the hinge. The shell is typically bilaterally symmetrical, with the hinge lying in the sagittal plane. Bivalve species are suspension feeders and are largely influenced by tidal amplitude, waste from rivers, rainfall, change in salinity or pH, and intolerable blooms of phytoplankton. Bivalve is the class where the Nylon Shell (Phapia undulata) belongs.
STATEMENT OF THE PROBLEM This study is aimed to determine the comparative morphological structure of Nylon Shell (Phapia undulata) in Tigbauan and Guimbal. Specifically, the study sought to answer the following questions: 1. Where is the best location to gather Nylon Shell (Phapia undulata) in terms of: a. size b. weight 2. Does the salinity, ph level and oxygen dissolved in the water affect the morphological structure of Nylon Shells (Phapia undulata). 3. Is there any significant difference in the size and
