Translucent Nudibranch

Photograph by Jennifer Hayes

This Month in Photo of the Day: Animals

Built to feed exclusively on corals like this spindly gorgonian, a translucent 1.7-inch-long (4.3-centimeter-long) Phyllodesmium iriomotense houses its branching digestive gland within tentacle-like cerata—outgrowths the animal can shed if under attack. This species is one of the few colorless nudibranchs.

本月每日一图的主题是：动物

以珊瑚（比如这种细长的柳珊瑚）为食、半透明、1.7英寸（4.3厘米）长的Phyllodesmium iriomotense在受到攻击时，会把它枝状的消化腺缩回到触手（比如裸鳃）中——就像那些断肢求生的动物。这种海兔是罕见的几种无色品种之一。
