A little perspective
Door leaf vs Elkhorn coral colony: length comparison
The colony width of an elkhorn coral colony is about 1.01 times the length of a door leaf.
A door leaf is the main flat panel of a door that swings or slides to open and close an entryway.
An elkhorn coral colony is a branching formation of the coral species Acropora palmata, found in shallow Caribbean reefs.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.

Defined examples — our methodology
The marked length is calibrated. Unmeasured illustration details are representative.
Elkhorn coral colony
Defined colony width: 2 m; defined specimen; range 1 m–3.5 m.
A defined mature elkhorn coral (Acropora palmata) colony 2 m wide and 1.2 m high. Branch growth and breakage produce irregular colonies; the basal reef substrate is excluded from both spans.

Why this measurement?
Why we use 1.981 m
We compare the length of a door leaf. This is an illustrative comparison value, not a claim that every example is the same.
