Red-Eared Slider Turtle's question about Vent Prolapse

Question

My Red ear slider turtle of 2 yrs old has a black Body part coming out of his body and then it protrudes back inside after 15-20 mins, is that normal. Please do let me know as i thought it is his male reprooductive organ protruding out when excited and it going back

Accepted Answer

The image in the link below is of a prolapsed penis of a Red Eared Slider Turtle, without examining him I cannot say what it is but hopefully the image should shed some light on this for you. Visit your Veterinarian if you have any concerns. Regards Dr Callum Turner DVM
