The rostrum is a broad and bluntly rounded tooth. The eyestalks are flattened, and the eyes (cornea) appear as dark patches mid-dorsally on the eyestalk
There is a gap between the propodus and dactyl on the large chela. In this case the large chela is the left one but it may be the left or the right. The hairs on the legs are used for sifting food from the substrate.
In this view one can see that the carpus of the small cheliped (foreground) is wider than is the merus. The propodus and dactyl are below and slightly out of focus; and the large chela is in the background.
