中文摘要 | 本研究以水肺潛水調查生物礁內棲性的軟體動物,其中四個科的二枚貝是珊瑚鑽孔生物的代表,鑽孔貽貝,開腹蛤,鷗蛤(Pholadidae,簾蛤(Venerinidae)等,其中以鑽孔貽貝(Lithphaginae)(Mytilidae)及開腹蛤(Gastrochaenidae)對珊瑚礁的侵蝕程度較大,而鑽孔貝在與死珊瑚及珊瑚礁石灰岩中的物種分佈與數量較藻礁多,且在死珊瑚中開腹蛤量為多,但是藻礁中多毛類數量較少。除了許多軟體動物之外,許多蠕蟲如多毛類、星蟲、甲殼動物和腔腸動物都利用此區為棲息地,而鑽孔貝類可以先在鬆軟的碳酸鈣棲息地上挖洞。許多藻礁內的掘穴中僅有空殼,表示物種可能死亡而推測數量也很大。本次採得貽貝科中石蜊屬Lithophaga及Musculus兩個屬共六種,並發現兩種新紀錄種貽貝(貽貝Musculns euminganus及石蜊Lithophaga Musculus)及一種珊瑚螺(Coralliophila striatus)及一種石磺(Onchidella orientalis)。 |
英文摘要 | In this research, we applied the SCUBA diving to investigate the infauna mollusca in the biological reef, especially in coralline algae reef and coral reef arownd the northern corner of taiwan. The representative reef dwelling mollusk including four family, Lithohaginae, Gastrochaenidae, Pholadidae and Venerinidae. Representative of the Lithohaginae and Gastrochaenidae are particular important agents in borsion of reef. The species number in limestone reef were more than coralline algae reef. The abundance of Gastrochaenidae in limestome (dead coral reef) were more than other habitats. Besides the mollusck, lots of invertebrates such as Polychaete, Sipuneula utilize the habitats. The microhabitats were drilled by infauna mollusk than occupied by other animals. We also found two new record species of Mytilidae and Coralliophilidae and one Onchidiidae. |
