Is my sulcata's plastron normal?

[cHrIsDeR13]

Hello everyone! I'm new to being a tortoise owner, so I'm naturally a little paranoid about the health of my new baby. My sulcata is around 2-3 months old, has a big appetite, and is very active. I recently realized that there are slight ridges on the bottom of his plastron. So my question is, are these ridges normal? Thank you in advance for your help!
