Earthworm
12 cm - Body length; representative.
An earthworm is a segmented invertebrate that lives in soil and aids in decomposing organic material.
A chosen 12 cm earthworm; length changes as the animal moves.
Defined examples — our methodologyThe body length of an earthworm is about 8 times the body length of a honeybee. Selected basis: a representative value for Earthworm; a representative value for Honeybee; approximate values.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.

A 15 mm worker honeybee (Apis mellifera), at the upper end of the cited 10–15 mm worker range. Body length excludes antennae, legs and wings. The 100 mg mass is a separate illustrative assumption.
