There is a functional difference between being pedantic about the word “functionally” and supplying relevant information.
My comment indicates that the animal can still die, your comment indicates it doesn’t age.
Do you see the meaningless distinction?
No, my point with “functionally” is that it can be killed.
Biological immortality is a very specific concept indicating an absence of aging and the absence of an increase in expected mortality along with age.
I just mean that something can still eat it. This is an easy concept to understand if you’re not focused on correcting people needlessly.
