西班牙披肩海蛞蝓 圣卡塔利娜島附近海藻上的西班牙披肩海蛞蝓 今天我們要見(jiàn)到的是一群雜色的海蛞蝓中的一種，叫做裸鰓類(lèi)動(dòng)物（與“謝謝”押韻），它們以其獨(dú)特的形狀和霓虹燈般明亮的顏色而聞名，有助于阻止捕食者。西班牙披肩海蛞蝓的火橙色鬃毛是由一種名為cerata的卷須組成，主要起鰓的作用。但是，這種鬃毛也保留了來(lái)自蛞蝓獵物?？亩疽?，它能使任何想要吞食的人遭受痛苦的刺痛。如果一只貪婪的海星無(wú)視這些防御措施，靠得太近而無(wú)法獲得舒適感，西班牙披肩海蛞蝓有一個(gè)B計(jì)劃：通過(guò)像膠狀翅膀一樣拍打整個(gè)2到3英寸的身體，裸鰓類(lèi)動(dòng)物可以飛入開(kāi)闊的水域快速逃生。

Today we're meeting one of a motley group of sea slugs called the nudibranchs (rhymes with 'thanks'), known for their unique, often complex shapes and neon-bright colors that help discourage predators. The Spanish shawl's fire-orange mane is made up of tendrils called cerata that mainly act as gills. But that mane also retains venom from the slug's prey—sea anemones—treating any would-be devourers to a painful sting. Should a ravenous sea star disregard these defenses and get too close for comfort, the Spanish shawl has a Plan B: By flapping its whole 2- to 3-inch body like a gelatinous wing, the nudibranch can flutter into open water for a quick escape.
