What type of fresh water turtle allows the young to piggyback ride?

Question

Round head, adult about 1 foot, young turtle 4-5 in

Answer 1

many pond turtles are social animals they stay together in large groups and young often climb on the adults back.

Answer 2

No turtle cares for its young. Like Han said- it is a turtle sunning with another on its back.

The description is not real helpful, but a common turtle that does this is the Painted Turtle.

Answer 3

the common yellow bellied turtle does that but are a lot smaller than a foot long.
