因為中國人對花膠的強大需求,生活在太平洋彼岸、有「全球最細海豚」之稱的小頭鼠海豚(Vaquita),正面臨絕種的威脅。
關注組織指出,小頭鼠海豚目前的數量,較 2011 年大幅減少九成,現僅存不多於 30 條。世界自然基金會(WWF)指出,小頭鼠海豚有可能會在數個月內絕種。
中國人愛吃的花膠,由在墨西哥加利福尼亞灣出沒的加利福尼亞灣石首魚(totoaba)魚鰾製成,但非法漁民使用刺網(gillnets)捕捉石首魚時,往往會波及在同一海域生活的小頭鼠海豚。石首魚目前亦已瀕危。

...In the papers Gillyweed – Drowning with Gills? and Revealing the Magic of Skele-Gro, both published in the Journal for Interdisciplinary Science Topics, students at the University of Leicester analyse two spells used by Rowling’s young wizard: Gillyweed, which enables its eater to grow gills and thus breathe underwater, and Skele-Gro, which repairs broken bones.If Harry were to open his mouth to allow water into his throat and out through the gills, it may be plausible
From Gillyweed – Drowning with Gills?Gillyweed, which is eaten by Harry Potter when he is attempting to swim to the bottom of a lake in the fourth book, Harry Potter and the Goblet of Fire, was investigated by natural science students Rowan Reynolds and Chris Ringrose. Looking at the size of Harry’s gills in the film adaptation of Rowling’s novel, they estimated them to be 60cmin surface area. They then estimated the oxygen content of the Black Lake, and the maximum oxygen use of swimming, and found that the average 14-year-old boy “would need to process 443 litres of water at 100% efficiency per minute for every minute he was underwater”, meaning that water would need to flow at 2.46 metres per second.
“This is extremely fast if Harry is to bring water into his gills through respiratory power alone. The velocity of normal breathing has been recorded as 1.30 metres per second; 2.46 metres per second is almost twice the velocity of normal airflow, which makes Harry’s gills unfeasible,” they write in the peer-reviewed student journal, which is run by the university’s Centre for Interdisciplinary Science and intended to give students practical experience of writing, editing, publishing and reviewing scientific papers.
“In the film, Harry is frequently seen swimming with his mouth closed, which is not how fish use their gills,” they add. “If Harry were to open his mouth to allow water into his throat and out through the gills, it may be plausible that he could breathe underwater. However, without doing this, it is simply not plausible that he could extract sufficient oxygen for survival,” they conclude.
