Snail crawling vs Red blood cell in a capillary: speed comparison
The speed of a crawling snail is approximately equal to the capillary transit speed of a red blood cell in a capillary.
DISTANCE IN ONE SECOND
Snail crawling is the slow movement of a snail as it glides along a surface using its muscular foot.

A red blood cell in a capillary refers to an erythrocyte moving through the body's smallest blood vessels as part of microcirculation.

Measurements, assumptions & sources +
Snail crawling
Speed: 0.001 m/s; example.
A chosen 1 mm/s crawl. Species, surface and conditions affect pace.
Defined examples — our methodology
The marked speed is calibrated. Unmeasured illustration details are representative.
Red blood cell in a capillary
Representative capillary transit speed: 0.001 m/s; representative; range 0.0005 m/s–0.002 m/s.
A representative red-blood-cell speed of 1 mm/s in a human capillary. Microvascular flow changes with vessel diameter, tissue, pressure and physiology, and individual cells deform during transit.

Why this measurement?
Why we use 0.001 m/s
We compare the speed of a crawling snail. This is an illustrative comparison value, not a claim that every example is the same.
A chosen 1 mm/s crawl. Species, surface and conditions affect pace.
