I have an eastern snake-necked turtle. Her name is Shelley. According to the guy who handed her to me, she was playing "Frogger" on the highway and lost. She has a crack on her plastron that runs from one side to the other, and is bleeding a little. The wound isn't gaping or displaced, so all she needs is R&R for 6 weeks and some silicone to keep water and air out. I'll check out the rest of her shell tomorrow for other cracks but so far it looks okay. I'll take her to a vet on Tuesday for some antibiotics and an x-ray.
