In life, this small crab varies greatly in form and color. Usually 

 it is irregularly mottled or blotched with light greenish yellow or 

 pale yellow on a darker olive-green ground-color, usually with a large 

 blotch or spot of pale yellow or whitish on the back of the carapace, 

 thus imitating the olive-green colors of the gulf -weed {Sargassum) 

 and the whitish patches of Bryozoa [Biflastra) with which the Sar- 

 gassu^n is commonly covered. Thus its colors are eminently protec- 

 tive, for it natui'ally lives in the open sea among Sargassxin.
