Dead shrimp or shed shell?

Hi, being a bit of a numpty, how can I tell if what I have in my tank is a dead shrimp or a shed exoskeleton?

 

Shell looks like something has ripped out of it and hollow.
A dead shrimp looks more solid and still have some colour to it... husks are white white white and see through in places.

 

you will know the difference if you find it. have you ever pulled skin off your arm after being sunburnt?????? thats what a molt will look like........say no more. a dead shrimp will be a dead shrimp or eaten....

 

Dead Amano shrimp tend to be pink, whereas the exoskeleton is just white.
