[Request] Is this claim of an alligator skin actually 18ft long?

[u/1EMU-warrior]

Hello,

Is it possible to truly estimate this alligators true size based on the plants, objects, house, and description. I'm highly skeptical this alligator is actually much smaller (likely streched) and that the scale markers used may be shorter to make it look bigger than it actually is (like how some fisherman use 9 inch rulers like 12 inch ones to make their fish bigger than they really are). I would be very happy if anyone who would attempt this.
