What is considered low cal tuna?

I just found canned tuna with 90 cals per 100g. I think it's too good to be true. Like, is it even real?

Also, I really am wondering if I can have a tuna salad that's like around 100 cals? Guess with this it might be possible...

Edit: y'all chill out, I eat tuna like twice a year maybe even less, I don't think there's any chance of me getting mercury poisoning 😭😭
