西嶼坪鐵針 (海蝕柱)

簡介

📍 概況：西嶼坪外海孤立的玄武岩海蝕柱群，因形如直插海底的鐵針而得名，為進階地形點。 🤿 環境：水深 12-28m，水下玄武岩石柱筆直陡降，通道與穿透海蝕拱門縱橫交錯，海流偏強。 🐠 生態：柱體表面生長茂密柳珊瑚海扇，迎流面常有巨型牛港鰺、金梭魚群及過境的白鰭礁鯊。 ⚠️ 須知：海蝕柱周圍容易產生下洗流與強烈迴流，僅限 AOW 具備抗流經驗者，必備象拔與流鉤。

📍 Overview: Solitary offshore basalt sea stacks near Xiyuping named after their needle-like upright spires. 🤿 Conditions: 12-28m deep. Sheer vertical basalt columns and interconnected swim-through arches swept by swift currents. 🐠 Ecology: Columns encrusted with gorgonian fans; upstream faces attract schooling barracuda, GTs, and reef sharks. ⚠️ Note: Downdrafts and turbulent eddies occur around the pillars. Advanced divers with SMBs and reef hooks only.
