惊~罕见的紫色海螺被冲上圣地牙哥海滩🐌
最近在圣地牙哥的沙滩上,游客们可能会注意到一些闪闪发亮、仿佛宝石般的紫色小贝壳。
加州大学圣地牙哥分校的史克里普斯海洋研究所科学家(Scientists at the University of California, San Diego’s Scripps Institution of Oceanography )指出,这些是名为 Janthina(洋紫螺) 的罕见海螺品种。牠们以鲜艳的紫罗兰色贝壳闻名,并能借由一种天然的「气泡筏」漂浮在海面上。
这些海螺因其贝壳呈现宝石般的紫色光泽而引人注目,仿佛散落在沙滩上的天然饰品。牠们原本栖息于亚热带至热带的开放海域,能够借由自然产生的「气泡筏」漂浮在海面上。由于近期海水异常温暖,洋紫螺被洋流带向南加州沿岸,才会在像拉荷雅(La Jolla Shores)这样的地区被发现。
