氣候變化已公佈了其最新的受害者：鯱螺(學名Limacina helicina)，一種捕食性浮游海螺，被(36)普遍稱為海蝴蝶分類組中的一員(“海蝴蝶”之名(37)來源於微小生物用來遊走的翼狀葉瓣)。在(38)最近《皇家學會學報B》刊載的一項研究報告中，來自美國國家海洋和大氣管理局(NOAA)及俄勒岡州立大學的科學家們指出：太平洋的PH正在不斷下降一換句話說，海水的酸化正在溶解鯱螺的薄殼。
研究人員收集了太平洋沿岸(從華盛頓到南加州之間)13個地點的海蝴蝶(39)樣本，並用掃描電子顯微鏡對其一一進行深入檢查。來自海岸的個體樣本中有一半以上(53%)的貝殼都(40)呈現出“嚴重溶解”的跡象，而在來自(41)海面上的個體樣本中僅有24%的貝殼受到溶解破壞。該研究的(42)首席研究員，來自NOAA的Nina Bednarsek指出那些受到影響的鯱螺的.貝殼都擁有“菜花”狀或者“砂紙”狀的紋理。
據該研究報道，嚴重損傷的貝殼數量與海洋表面附近“欠飽合海水”百分率之間呈現出“強烈的正(43)相關”。研究人員推斷出，“自該區域工業化時代以前的海洋條件算起，近海棲息地(由於人為導致的海洋(44)酸化)引起的貝殼溶解已經翻了一倍，到2050年可能會增至三倍，這真是個(45)糟糕的預言。此外，這對生態系統的更廣泛影響並不明確，因為受傷的外殼會讓鯱螺更難以抵禦感染、保持浮力及逃脫捕食者的獵殺。
