How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 40 kg for the adult mass of an emu; the recorded range is 30 kg–55 kg.
- The adult mass of an emu: This is a representative comparison value; individual specimens or conditions can vary.
- 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.
