An Introduction to the Hatchlings
They also have very different undersides.
The experiment (yes, that’s the reason for all the hard work so far!) will begin in September. We’ll be investigating whether PIT (Passive Integrated Transponder) tags affect the growth and development of painted turtles. A PIT tag is a microchip encased in glass injected into a turtle’s body for identification. A scanner reads the tag and produces a number unique to its bearer. For the experiment, three turtles will be designated to each tank: the first injected with a tag, the second untagged, and the last operated just like the first but not tagged. All turtles will be weighed and measured each month.
