Another photo of the species. Dave Cowles, July 2001 Enlargements of the right and left chelae from the picture above. Dave Cowles, July 2001 The broad abdomen of this species is soft, somewhat like leather; especially in the distal yellow portion visible above. This appears to be a male abdomen. See the photos below to compare with a female abdomen. Photo by Dave Cowles, July 2001
The underside of this female's abdomen is soft in part of it but has a rounded, hardened shield across the tip. She is carrying eggs (see below). Photo by Dave Cowles, July 2012
This is the same female as shown above. She is highly defensive of her abdomen but the crevice seen in this view shows that she is carrying many bright orange eggs.
