Red Eared Sliders

I put it up as a separate spotting. Hopefully somebody might be able to Id it. Thnx so much though.

i don't know.

I am glad that you agreet hat the fourth one is different.There are various species in this pond. Painted turtle,box turtle and some tortoises.
Could this be a Western painted turtle. I saw one recently.

The first 3 look like they are Trachemys scripta, defenately a Trachemys sp.
The last one i am not going to hazzard a guess.

Thnx dungeonmastershu!
