A little perspective
Sesame seed vs Copepod: length comparison
The length of a sesame seed is about 1.5 times the body length of a copepod.
A sesame seed is an oil-rich edible seed produced by the sesame plant and used whole, ground or pressed for oil.
A copepod is a tiny aquatic crustacean found in marine and freshwater environments, playing a key role in aquatic food webs.
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.

Example seed: 3 mm long, 3 mg.
Defined examples — our methodology
The marked length is calibrated. Unmeasured illustration details are representative.
Copepod
Defined body length: 2 mm; defined specimen; range 1.5 mm–2.5 mm.
A defined 2 mm adult calanoid copepod specimen with a 10 microgram wet mass. The body span excludes the long antennules; species, life stage and hydration produce wide variation.

Why this measurement?
Why we use 3 mm
We compare the length of a sesame seed. This is an illustrative comparison value, not a claim that every example is the same.
Example seed: 3 mm long, 3 mg.
