Take the hongshuxian (Geloina coaxans) a shell-fish so large that you can't cover it with one hand. Buckets of them used to be a common sight in harbor markets. Last year Wu came across one specimen while carrying out a study of Taiwan's West Coast ocean resources with the TESRI. He hadn't seen one previously for more than a decade.
例如十幾年來巫文隆再未見到過去漁港常出售大型、手掌無法握滿的紅樹蜆，直到去年他與台灣特有生物中心進行西部海岸資源調查，才再次發現看來碩果僅存的一個紅樹蜆。
