Marsupial cat vision: the science and the numbers

Dasyurus hallucatus · order Dasyuromorphia · Mammals: all the numbers

Its sharpest vision resolves 2.675 cycles per degree, against 63.75 for people in this dataset.[6][7] Both eyes see the same 125° in front of it.[8]

The marsupial cat (Dasyurus hallucatus) is a mammal in the order Dasyuromorphia. 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, field of view 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 2.675 cycles per degree: the finest stripe pattern it can tell apart from grey.
  • Both eyes see the same 125° in front of it (binocular overlap), where depth is judged best.
  • Activity pattern: nocturnal.

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.
