Bar length measures mass, not physical size.

A little perspective

The mass of 80 kilograms and the defined wet mass of Giant barrel sponge are approximately the same.

Measurements, assumptions & sources +

80 kilograms

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

NIST — SI conversion factors

Giant barrel sponge

A defined 1.2 m high giant barrel sponge (Xestospongia muta) with an 80 kg wet mass. Colonies grow in irregular barrel forms; height excludes the reef substrate and the central cavity is open.

Smithsonian Ocean — Sponges

The marked defined wet mass 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.

  • Giant barrel sponge uses a 80 kg central value within a recorded range of 30 kg–180 kg.
  • Giant barrel sponge is labelled defined specimen; 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.
