I dont know but maybe by the size
There is no way to tell how old a sea turtle is or even how long they live. The best estimate is that they can be up to eighty years old when they die. There are no rings or lines on a turtle shell that increase with age to tell how old the turtle is. A typical sea turtle reaches breeding age around 25-30 (for loggerheads). After a turtle does become an adult, it is anyone's guess how old it is.
Ask it. Thats a stupid answer
look how many wrinkles it has
you can tell how old a turtle is by counting the squares on their back...
the awnser is to look how big its spieces is and see how big it is.
flip it over.
You count the rings on one of his circles on his back.
An old turtle is simply called a turtle. There is no name for an old turtle; however a baby turtle is called a "Hatchling". YOUR VERY WELCOME BUDDY :)
unless you had it from the time he was born, you can't tell. counting the rings on it's shell DOES NOT work.
according to what I've read, there is no way you can tell unless you record the day it was born..
They will be bigger with more spots on the shell. Usually you can tell just by looking at it.
just ask chuck Norris i am sure he has ate a few.....
