Does anyone know why my 10+ yr old corn snakes tail has gone like this. What could it be? View attachment 393435

Looks like dehydration, but odd for it to exclusively affect the tail. Thrasops (he's on this forum) might know. Why not send him a message?

 

Has it appeared suddenly, or developed gradually? Can he move his tail normally? It looks like a tail of really underweight or dehydrated snake ( which yours doesn't seem to be ), so my other guess is muscle wastage for some reason - but that would have happened gradually?

 

It does seem odd.

 

A photo of the whole snake would be handy. In the top picture there seems to be a change mid body where the spine transitions from the usual loaf of bread cross section to a defined ridge. Feeding records would also help as well. I would agree, based on the two images it looks like a nutrition and or dehydration issue.
