Razorback turtles are semi-aquatic reptiles, usually divided into two types: red-spotted razorback turtles and yellow-headed razorback turtles. To tell a male from a male a razorback turtle, it's best to look at the following details:
The tail of a male razorback turtle is longer than that of a female.
The bottom of the male turtle shell isconcave, while the female is flat.
Two spherical objects can be seen under the skin at the base of the turtle's legs and tail. The male is larger than the female.
Under the turtle's lower jaw, males have a raised patch of skin that females do not.
These signs can help identify the gender of a razorback turtle. Of course, it is best to ask a veterinarian or reptile expert to check and confirm.
