鹦嘴鱼 东内格罗斯省沿海的鹦嘴鱼 这些色彩鲜艳的鹦嘴鱼正游出菲律宾的内格罗斯东省海岸。超过80种鹦嘴鱼大量生活在世界的热带海洋中，在印度-太平洋地区发现的物种多样性最多。这些厚重的鱼有巨大的鳞片和融合了牙齿的喙，它们用来勤奋地刮去礁石和岩石上美味的藻类。它们还吃珊瑚，用喉咙里的盘状牙齿把珊瑚磨碎。研究人员表示，鹦嘴鱼通过食用会抑制珊瑚生长的藻类，在珊瑚礁的健康中发挥着关键作用。它们还有助于补充这些热带珊瑚礁附近的白色沙滩。为何?鹦嘴鱼消化了珊瑚的可食用部分后，就会排泄出剩下的沙子——大量的沙子。在某些物种中，一只鹦嘴鱼每年可以排泄近1000磅珍珠白色的沙子。但不要介意——一些琐事最好不要细想。

These brightly colored parrotfish are swimming off the coast of the Negros Oriental province in the Philippines. Over 80 species of parrotfish live in abundant numbers in the world's tropical seas, with the most species diversity found in the Indo-Pacific region. These thick-bodied fish have large scales and a beak of fused teeth they use to diligently scrape off delicious algae from reefs and rocks. Some also eat coral, which they grind up with plate-like teeth in their throats. Researchers say parrotfish play a critical role in the health of coral reef by eating algae that can choke off coral growth. They also help replenish the white sandy beaches near these tropical reefs. How? After parrotfish digest the edible parts of coral, they excrete what's left as sand–a lot of sand. In some species, a single parrotfish can poop almost 1,000 pounds of pearly white sand each year. But never mind that–some trivia is best not to dwell on.
