Yep, I have 12 turtles and in the summer they spend most of their time on land, basking and roaming around my garden. They only really return to the water at night.Yeah many people don't know they can get quiet big in the end. I see wild painted turtles get to around 16 inches in length around here, granted that's a really old turtle, but they also have massive ponds to live in. Atleast with musk's they tend to stay around the size of your hand in most cases.
Most people also don't realize that just because a reptile spends most of its life in the water doesn't mean that it doesn't need to come out and sun bathe everyday to maintain body temp.
