That's what I was thinking! Yes, we plan on keeping him (not sure if its a him lol) I'm currently trying to set up an enclosure since he was brought into our care on a whim. Thanks for the care guide, this is our first tortoise so I was glad I found this forum - there seems to be a ton of great information. I'm banking on going to our local reptile shop to see if I can get some more guidance for enclosures too since I know he's gonna need a ton of space.Hi there - welcome to the forum. It is a Russian tortoise, who looks like they're in need of some tlc. Will you be keeping him/her? Lucky you and your friend found them, especially if they were by a river.
Here is a care guide to get you started: https://tortoiseforum.org/threads/the-best-way-to-raise-any-temperate-species-of-tortoise.183131/
