A little more perspective
NOAA distinguishes the larger Antarctic reference from the roughly 90-foot upper size it describes for the North Atlantic and North Pacific. The displayed value rounds 110 international feet to 33.5 meters and remains an approximate reported size.
The whale stays horizontal. Its full body length is compared with the explicitly labeled widths and wingspans of other subjects in span mode. The illustrated fin span is a visual proportion, not a separately sourced width.
Quick facts
A 33.5-meter body-length reference, rounded from NOAA’s reported upper size of about 110 feet for Antarctic blue whales. This is length from snout to tail, not standing height or a species average.
For a presentation or a research note, include the subject, the measurement definition, and the measurement used. A picture alone cannot explain those choices. The comparison guide explains how to export an image and its source notes together.
