中文注释:在澳洲,宁静的蓝绿珊瑚礁和海水相映成趣。珊瑚生活在全世界的热带水域,通常出现在太阳光线可以直射到水藻的海水表面。珊瑚从水藻通过光合作用产生的副产品来获得它们大部分营养物质,珊瑚的触须带有刺且有毒。它们经常在晚上的时候伸出触须,抓捕一些浮游动物甚至是小鱼。照片为国家地理杂志2001年4月的《追捕小须鲸》拍摄,未发表。内容摘自该文。 作者: Flip Nicklin
珊瑚礁 澳洲 图片故事:高清壁纸:英文注释:Coral Reef, Australia, 2001 The serene blues and greens of a coral reef blend in with waters off Australia. Corals live in tropical waters throughout the world, generally close to the surface where the sun's rays can reach the algae. While corals get most of their nutrients from the byproducts of the algae's photosynthesis, they also have barbed, venomous tentacles they can stick out, usually at night, to grab zooplankton and even small fish.
