The yellowline arrow crab, on average, is 3 to 6 centimeters in length.

 

What makes the yellowline arrow crabs unusual is their long, spider-like legs, and and extremely pointed head. The eight legs are extremely long, more than three times the length of their body, and resemble the legs of a daddy long-legs spider. The entire body of the yellowline arrow crab is a medium golden brown in color. Along the dorsal side of the crab's body are stripes that are white, brown, or gold depending on the individual crab. The tips of their legs are a deep violet in color. As crabs grow, they occasionally shed their exoskeleton. The new skin hardens with calcium carbonate, obtained from sea water and by ingesting the old shell (Humann 1992, and Snyderman and Wiseman 1996).
