Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.

A little perspective

The length of 50 centimetres and the representative total length of Platypus are approximately the same.

50 centimetres

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

NIST — SI conversion factors

Platypus

A representative adult platypus 50 cm from bill to tail and 1.5 kg. Sex and population affect size, and the broad tail is included in total length.

San Diego Zoo Wildlife Alliance — Platypus

The marked representative total length is calibrated. Unmeasured illustration details are representative.

The two selected measurements are approximately equal.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

  • Platypus uses a 50 cm central value within a recorded range of 40 cm–63 cm.
  • Platypus is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
  • The recorded ranges overlap, so the ordering can vary even though the central values differ.
