Arabian camel vision: the science and the numbers

Camelus dromedarius · order Artiodactyla · Mammals: all the numbers

Its sharpest vision resolves 10.4 cycles per degree, against 63.75 for people in this dataset.[6] Its activity pattern is diurnal.[13][1][14][15][16][17][18]

The Arabian camel (Camelus dromedarius) is a mammal in the order Artiodactyla. Its eyes belong to the vision type Grazing ungulate panorama: two cone types, a horizontal band of sharp vision and a near-panoramic field with a blind area behind the head. Measured in this species: sharpness, foveas and night vision. Measured core: measured values on at least 3 of the 6 dials.

This is a simulation built from published eye measurements, not what the animal experiences.

What stands out

  • Its sharpest vision resolves 10.4 cycles per degree: the finest stripe pattern it can tell apart from grey.
  • Activity pattern: diurnal.

The six dials

Evidence levels: how the tiers work. "Measured" means a value measured in this species; "Estimated" values come from a close relative or an eye-size formula. The last column gives the values for people from the same catalogue.

Every value cites its sources (all sources). Values were extracted from these works and converted (units, medians, derived values); changes are ours, and the listed sources do not endorse this site. Data: catalogue-v1, built 2026-09-29. Accuracy notes: how accurate is this? Method: how we know.
