:I have three baby turtles which are about to turn a year old in july or so. I was wondering about their sexes and was wondering if I could get some help because the nails and tail things didn't quite work. One is 2.75" long and 2.75" wide and the other two are 2.25" long and 2" wide. The first one is a lighter color green with a ride stripe of top if it's head and seem to have the pounch type thing on the bottom of its shell for help with "mounting." The other two are smaller by quite a bit but are much taller and a darker shade of green without a ride stripe on their heads. I can't tell with the tail or claws because their sizes are so different. Thanks!
