HELP, I'M A WOODLOUSE - GET ME OUT OF HERE! (WOODLOUSE SHEDDING SKIN)

We were learning about classification of species, in particular invertebrates. The very next day when walking in Epping Forest we came across this woodlouse in a bit of rotting tree trunk. It's an arthropod and it is also a crustracean. As such it has a hard exoskeleton which it sheds from time to time as it grows. I have never seen this in my life before so it was quite interesting. I guess it was all transparent while he was in it, but goes white after he gets out of it.
