Some useful points when traveling with Turtles:
When transporting turtles, always make sure that you do not put them in bags or containers that are sealed and/or contain water.
When traveling like this there is a high likelihood of drowning.
Moving turtles in dry pillow cases is an option as they can breathe through the case (ensure that you do not soak this before putting the turtles in, as they could suffocate if there is not enough oxygen).
