My RES

There was a 4" rule that was applied to the shell, but (at least on the federal level), I think that it has been scrapped. If memory serves, the shell had to measure at least 4" in width (>4" from any angle, edge to edge of carapace).

Hmm then I either got mine under the legal limit or it hasn't grown at all....but it has so it was sold under the legal limit. I got it in FL. along with another one but the other died :(
 
i've seen baby turtles sold in dozens of pet shops around the country, but it does seem to be more common in FL. they just stick up a sign that says "turtles under 4" sold for research purposes only" and that's about it. i guess the law isn't really enforced, but it's a pretty stupid law anyway.
