This pic is from when I went to the New England Aquarium in Boston a while back.

The internal organs of a red eared slider turtle, this particular RES is a female:

Sometimes, with turtles being as small as they are and seeing how big their feet are, how long their heads, necks, and tails are and that they can hide in their shells – it is easy to forget about all the other internal organs that they have that keep them alive and healthy. Turtles are truly wonderful creatures of the Creator!

  3. I hope you’re still answering these posts. I have a 1 1/2 inch RES and it seems to be shedding some skin under its neck. Do they do that? It’s in a big enough tank, warm enough water, is eating fine, active, drying off (no UVB lamp yet, tho… soon… need 220 v and can’t find it here in Jordan). Any ideas?

    1. they shed all their skin, sometimes just one body part at a time – even just the neck. They tend to shed more when the water is hotter, so just be sure the water is the correct type of warm for your pet turtle. 75 F is the ideal

  4. Help. I have a very young RES maybe 6 months at the most, and 1inch in diameter. He/she is not getting bigger around, just getting a lot thicker. Even his/her shell is puffing up like a volcano. I’m afraid he/she is going to explode. What am I doing wrong?

  5.
