On Lake Okeechobee, no person may take or sell any peninsular cooter (Pseudemys peninsularis), Florida red-bellied turtle (Pseudemys nelsoni), Florida snapping turle (Chelydra serpentina osceola), or Florida soft-shelled turtle (Apalone ferox) having a carapace length of less than eight inches.
So as long as it's not from there I guess you're good to go.
