A little perspective
Plum vs Cleaner shrimp: length comparison
The body length of a cleaner shrimp is about 1.1 times the fruit diameter of a plum.
A plum is a sweet, edible fruit produced by trees of the genus Prunus, containing a single hard stone.
A cleaner shrimp is a marine crustacean that removes parasites and dead tissue from fish, forming mutualistic relationships.
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.

Why this measurement?
Why we use 5 cm
We compare the fruit diameter of a plum. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 3.5 cm to 6.5 cm.
A defined medium raw plum 5 cm across and 66 g in mass. Cultivar, ripeness and growing conditions vary; stem and leaves are excluded from the fruit diameter.
