簡介:"MolluscaCuvierina columnella筒蝶螺科筒蝶螺Cuvierina columnella, or Cigar Pteropod, is also known as the "Turtle Head Pteropod" in Chinese, because the rounded end of its cylindrical shell resembles the head of a turtle. It also looks similar to medical capsules. The shell is open at the front and when alive, it is transparent or semi-transparent with a purplish-brown color. After death, the shell becomes an opaque grayish-white. The cylindrical shell is quite sturdy, so complete specimens are relatively easy to collect. The Cigar Pteropod is found throughout the temperate and tropical seas of the world. NMNS records show that it has been collected from the waters of Pengjia Island in northeast Taiwan, off the coast of Hualien, around Lanyu in Taitung, the waters off Lyudao, off the coast of Manjhou in Pingtung, off the coast of Hengchun in the southwest and in the South China Sea near the Dongsha Islands. 筒蝶螺Cuvierina columnella又稱為「龜首駝蝶螺」,因為牠們末端圓鈍的長筒狀體殼,形似烏龜的頭部,又像一顆裝藥用的小膠囊。牠們體殼的開口同樣在前端,活體時體殼呈透明或半透明的紫褐色,死後體殼變為不透明的灰白色。圓筒形的體殼構造較為強固,因此較容易採得完整的標本。 普遍分布於全世界的溫帶及熱帶海域,目前科博館的採集紀錄包括台灣東北 部彭佳嶼附近海域,東部的花蓮外海、台東的蘭嶼、綠島附近海域、屏東的滿州外海,以及西南部的恆春外海及東沙島附近的南中國海等海域。 "
