Brain coral colony
A brain coral colony is a living mound-shaped formation of coral polyps that secrete a grooved, dome-like calcium carbonate skeleton.

Bar length measures mass, not physical size. Both bars start at zero kilograms (kg). Pictures identify the objects only.
A little perspective
1 US ton is about 1.01 times the skeletal wet mass of a brain coral colony.

1 US ton
Mass: 907.2 kg; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Brain coral colony
Defined skeletal wet mass: 900 kg; defined specimen; range 200 kg–1.8 t.
A defined massive brain-coral colony 1.5 m across with a 900 kg wet skeletal mass. Species, growth form and cavities vary; the living grooved dome, not attached reef rock, defines the diameter.

- Comparing
- Mass ↔ Defined skeletal wet mass
- Relative size
- 1 US ton is about 1.01 times the skeletal wet mass of a brain coral colony. 1 US ton is approximately 0.798% greater than the skeletal wet mass of a brain coral colony.
How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 900 kg for the skeletal wet mass of a brain coral colony; the recorded range is 200 kg–1.8 t.
- The skeletal wet mass of a brain coral colony: This is an illustrative comparison value, not a claim that every example is the same.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
Mass is distinct from weight: an object’s mass stays the same as gravity changes.
