The smaller of these two Hermit Crabs, Pagurus bernhardus, is having a tough time of it. Firstly it appears to have lost it's front claws when changing skin & now it has chosen to exchange it's small shell for one that is far too large for it, also a larger Hermit Crab then trys to attack the smaller one. I must admit we did step in & help the little fellow, see the two videos below.
