The Puffer Forum

I just received this puffer and am I wondering if these circles on its back are normal, scars, or something worse? They seem totally superficial, not jutting out of the skin or anything which makes me think it’s a scar maybe from another puffer bit.
Thanks in advance

You are correct, it is a puffer bite.
