🐚Blue glaucus

Glaucus atlanticus Forster, 1777

大西洋海神海蛞蝓（學名：Glaucus atlanticus），也叫“蓝龙”、“蓝天使”、“蓝海燕”、“蓑海牛”等，是一種藍色、小型的遠洋翼蓑海蛞蝓，海生腹足綱海神鰓科軟體動物。這些海蛞蝓都是浮游生物：牠們上下顛倒的，利用水的表面張力來維持在水面，讓風和洋流把牠們帶往其他地方去。大西洋海神海蛞蝓的身體上的顏色可幫助牠們偽裝：牠們藍色的一面向天，與海水的顏色融合在一起，使海上的獵食者找不到牠們；而牠們向海底的一面則是銀灰色，與海面上折射天空的顏色融合在一起，令海裡的獵食者也找不到牠們。本物種以其他中上層的浮游生物為食，包括有毒的管水母葡萄牙戰艦。這種海蛞蝓會在進食過刺胞動物之後，把其刺胞儲存在從其自身組織內，以防禦捕食。人類處理這些海蛞蝓時有機會會被這些儲起來的刺胞刺中，令人感到非常痛苦。
