This species is very variable in colors, but the tints are evidently 

 decidedly protective. The mottlings of yellow, olive, and brown 

 closely resemble the colors of the stained and weather-beaten rocks 

 and dead algae among which it usually lives. 



In life, the ground-color of the carapace is most frequently dull 

 olive-green, yellowish, or yellowish-brown, sometimes dull gray, more 

 or less covered by irregular mottlings of darker brown, reddish, or 

 dark olive, usually darkest anteriorly, where the transverse ridges 

 are often edged with reddish or dark brown, making them more con- 

 spicuous ; large chelae are often plain light brown or reddish brown, 

 usually with pale tips, but in some cases they are blotched with 

 darker brown, or tinged with bright red on some parts, especially at 

 the jomts. The pereiopods are usually banded with darker and 

 lighter brown.
