Minke whale vision: the science and the numbers

Balaenoptera acutorostrata · order Cetacea · Mammals: all the numbers

Its sharpest vision resolves 4.125 cycles per degree, against 63.75 for people in this dataset.[6][7] Its activity pattern is diurnal.[16][17][18]

  • 4.125cycles per degree (sharpness)Measured

The minke whale (Balaenoptera acutorostrata) is a mammal in the order Cetacea. Its eyes belong to the vision type Small prey mammal (UV): two or three cone types, often including ultraviolet, low sharpness and a near-panoramic field. 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 4.125 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.
