I have a male turtle that has a white spot on his shell and I was wondering if you can tell what it is. It is not soft or smelly or anything. It is just white and sometimes more clearish in the water. Almost skin color.
Any Ideas?
It's hard to tell from the photo. Could you possibly give us another much closer up and when the shell is dry?
One possibility is it's shedding, though it's awfully bright for typical shedding. another possibility is fungus growing underneath a scute that loosened but didn't fall off and trapped water underneath. A shell infection - fungus or bacteria - won't be soft and stinky in the early stages.
If it looked like that after a scute peeled off, than my opinion is that it's may be exposed bone - that the scute came off too soon. Did anyone perchance help peel the scute off? Closeup dry pictures would be helpful.
It's hard to say. A bone layer would be much whiter, so it could be only partially exposed. What is the texture like? Is it smooth like the other parts of the shell?
