How To Tell The Age Or Sex Of A Turtle

How do I know if my turtle is a boy or a girl?
And how do I know how old my turtle is?

Hi Valerie,

Lots of people have the problems you have.

First, here's how to tell the sex of a turtle. You will pay attention to two body parts.
1. Look at the plastron. That's the bottom shell. If it is concave -- dents upward toward the inside of the turtle -- you have a boy.
2. Look at the tail. Boys have longer and thicker tails. Or course, this helps you only if you can see other turtles like yours. You didn't send a picture, so we can't help you more than that.

Second, you want to know the age of a turtle. The only real way to know is to be there when the turtle is born. If the turtle is young, size can help you if you know what is normal for the type of turtle you have.

Some people think that you can tell how old a turtle is by counting the rings on its shell the way you can with a tree, but that isn't true.

Keep it slow and steady,

Shelly

A friend of mine brought in two very very young snapping turtles to give a teacher who works at the local wild life sanctuary (though I don't know her because i have no classes with her). He said it was because he didn't want them getting hit by a car or something.
We were trying to guess their ages and I noticed how soft their plastrons were. I've never seen a turtle with one so squishy. Is that a normal thing? I'm guessing that its because of their age, and if so, when do they begin to harden?

You can tell the sex of a turtle by also its size. In most species, the female is bigger than a male.

there is another way to tell if a turtle is male or female. look at its tail, if its butt hole is farther down the tail its a male. If the hole is closer to the shell its a female. Hope that helps :) I took my 2 red-eared sliders to pet smart to make sure.

Concave means dented in. I always remember by thinking of a cave.

Convex means bulged out, by the way. Just saying.
