水下的世界裡，小蝦小蟹是如何躲避天敵的？手中的雙螯，似乎無法有效抵禦體型較大的捕食者，因此演化出匿蹤的能力。將體色改變成近似棲息的珊瑚顏色，藏匿其行蹤，以躲避天敵。圖1拍攝於墾丁合界，鄰近岸邊約水下15米處，俗稱的「糖果蟹」，棲息地在佈滿骨針的粉紅色棘穗軟珊瑚上，因此有別於其他螃蟹的特別體色作偽裝。圖2、3是白色與橘色的海鞭蝦，拍攝於基隆潮境公園，鄰近岸邊的水下約20米處，牠們的體色會根據居住海鞭的顏色，而改變其體色。

In the underwater world, how do shrimps and crabs avoid their natural enemies? As their pincers are not effective in fending off larger predators, they have evolved the ability to conceal themselves. For example, they can change color to blend in with their coral host. Image 1 was taken at Hejie, Kenting near the shore at a depth of about 15 meters. The soft coral crab, also known as the candy crab, lives among pink soft coral. It differs from other crab species, especially in terms of its ability to camouflage itself. Images 2 and 3 are of white and orange whip coral shrimp, both of which were taken off of Keelung’s Chaojing Park, near the shore at a depth of 20 meters. The color of this shrimp changes according to the color of the whip coral.
