鸌形目 Procellariiformes

鸌形目 Procellariiformes，來自拉丁文的 procella (風暴) 和拉丁文的 -fōrmis (形狀)，意思是「風暴形狀」，說明是這些動物通常在生活在海上，飛行在暴風雨和其他惡劣天氣條件下。

Procellariiformes, from procella (“storm”) and Latin -fōrmis (“-shaped”), in reference to the fact that these animals are normally found in the open sea, flying through storms and other adverse weather conditions.
