This photo was taken in the lagoon at Coconut Island, Hawaii. I worked there for seven years and Kaneohe is one of my favorite places. Because the little island is preserved, the reefs are still intact—paradise.

小丑熱帶魚，土康貝西羣島，印度尼西亞

Found in coral-rich seaweed reefs in the Pacific Ocean, clown triggerfish, such as this patterned juvenile in Indonesia's Tukangbesi Islands, are master predators. The fish blow streams of water at the sand to expose hiding prey, then use their powerful jaws and rows of sharp teeth to crush through hard-shelled reef creatures such as sea urchins, clams, snails, and crabs.

熱帶小丑魚，一般可以在太平洋海域多珊瑚、多海藻的羣礁地區發現，例如這一條就出現在印度尼西亞土康貝西羣島（Tukangbesi Islands）的海域。熱帶小丑魚雖然身材不大，但卻是精於捕獵的食肉魚類，主要的捕獵目標包括：海膽、蛤蚌、海蝸牛、蟹等等，它會吹動水流沖走沙粒從而讓獵物暴露，然後以它強力的嘴巴和尖利的牙齒捕獵食物。
