Field experiments were conducted in Hsingda harbor to investigate P. viridis byssus response on the survival condition of adjacent conspecific and heterospecific feeding habits; and P. viridis byssus in anti- predatory responses on the sympatry, allopatry, survival condition, hunting habbits, differences in body size and morphology of predator were also explored. Chi-square test was used to identify the response variations on P. viridis byssus ( trap no escape, trap escape, no trap ) , and differences between the numerical abundance and diameter of byssal thread were analyzed. The results found that the response was not significant difference between the survival and death of adjacent species; however, significant difference with sympatric, filter feeders, such as Crassostrea angulata, Thais clavigera and Thais bufo, was identified. The results also showed that the secretion of byssus by P. viridis form a anti-predator responses to competitive filter feeders and specific drill hole carnivore.
