A cleaner shrimp is a marine crustacean that removes parasites and dead tissue from fish, forming mutualistic relationships.
Also known as: skunk cleaner shrimp, Lysmata amboinensis
How big is it?
5.5 cm long
Also 2.165 in
Defined body length · defined specimen
Typical recorded range: 4 cm to 7 cm.
A little perspective
About the same scale as Antarctic krill.
Antarctic krill: Antarctic krill (Euphausia superba) are small, shrimp-like marine crustaceans that serve as a vital food source for many Antarctic animals.

Cleaner shrimp
A defined 5.5 cm skunk cleaner shrimp measured from rostrum to tail fan. Long white antennae extend beyond and are excluded from body length.
Smithsonian Ocean — Cleaner shrimp
The marked defined body length is calibrated. Unmeasured illustration details are representative.
Antarctic krill
A defined adult Antarctic krill (Euphausia superba) 6 cm long with a 1.5 g wet mass. Body length excludes the antennae; sex, maturity and feeding condition affect size.
Australian Antarctic Program — Antarctic krill
The marked defined adult body length is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 5.5 cm
For comparison, this page uses defined body length. This is labelled defined specimen: an explicit comparison model rather than a claim that every example has the same value. The recorded range is 4 cm to 7 cm.
