It is unknown exactly why, but Spark has dropped her big claw. This was about 4 days ago. However, she (its official) has lived and continues to thrive, and has not dropped futher limbs. She is eating a lot and I've seen her drinking and bathing frequently. She is a good crab and we hope she pulls through:) Wish her luck?
Spark without her big claw. It should be opposite her little one in the picture. If you don't know a lot about crabs and can't see it, just take my word for it that it's not there and is supposed to be:)
 
    Spark is up from his first molt. Color is a bit dull, but he didn't have much of an appetite before going down. Kind of a blueish purple color, but toned down. he is very alert and switched shells upon surfacing (yay!) upon being picked up, rushes of water poured out, proving that Spark has been quite  busy swimming in the 6 hours he's been up:) I am so happy to see my baby has survived, upon arrival home Spark did not move for days, being very lethargic and downcast.
