how to tell the sex of soft shelled turtles!

Question
how can i tell the sex of a soft shelled turtle? and how big can they grow?

Answer
Adult sizes for the average Softshell is also one of the easiest ways to tell the sexes.

Females can get from about 8-18" long measured in a straight line over the shell. Males go fom 6 to 10".

Males also have longer, thinner tails with the cloacal opening further from the base than the female's is.
