A little perspective
Raspberry vs Sea angel: length comparison
The fruit diameter of a raspberry is approximately equal to the body length of a sea angel.
A raspberry is an edible fruit from the Rubus genus, composed of many small drupelets and commonly red in colour.
A sea angel is a small, transparent swimming sea slug with wing-like appendages, found in cold ocean waters.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.
Measurements, assumptions & sources +
Raspberry
Defined fruit diameter: 2 cm; defined specimen; range 1.5 cm–2.5 cm.
A defined ripe raspberry 20 mm across and 4 g in mass. Cultivar, ripeness and growing conditions produce substantial variation.
Defined examples — our methodology
The marked defined fruit diameter is calibrated. Unmeasured illustration details are representative.
Sea angel
Defined body length: 2 cm; representative specimen; range 1 cm–4 cm.
A defined 2 cm adult sea angel modelled on Clione limacina. Body length excludes the extended wing-like parapodia; species, maturity and posture change the span.
The marked defined body length is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 2 cm
We compare the fruit diameter of a raspberry. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 1.5 cm to 2.5 cm.
A defined ripe raspberry 20 mm across and 4 g in mass. Cultivar, ripeness and growing conditions produce substantial variation.
The marked horizontal span follows the measured feature, not the edges of the image. How calibrated comparisons work →
