I'm not sure if this is an abrasion or what. It just appeared on my Portunus sayi within the last day or so. Her last shed was a couple weeks ago. She does swim around a lot, especially when there's food in the water, so she could have banged into something. I'm just worried that it may be a sign of some kind of nutritional/calcium deficiency? She eats frozen prawns and fish...
(It's the lighter orange spot on her right front claw's elbow... in the left of the picture.)
