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 (B(ftnstt-a) with which the Sur- 

 </(isxum is commonly covered. Thus its colors are eminently protec- 

 tive, for it naturally lives in the open sea among Sargasswn.
