desert tortoise develops thin white lines between scutes on shell
i am not sure exactly how old my tortoise is, but believe him to be between 13-17 yrs of age. he is in an enclosure for the winter, we regulate the heat, and have a 125 watt solar glo uva/uvb bulb. he appears happy, and his appitite has not changed much, however, has slowed. (chalked it up to winter in MN) today when i was feeding him i knowticed he has developed some thin white lines between the scutes of his plastron. i am sincerely hoping this is a growth issue that i have not yet encountered in my 4 years with him.
