[20] However, this explanation does not account for circular pupils that can be closed to a very small size (e.g., 0.5 mm in the tarsier) and the rectangular pupils of many ungulates which do not close to a narrow slit in ...

This is because the melanocytes of the RPE do not derive from the neural crest.
[47] [49] The ears are rounded and the eyes have a round pupil. [47] The snout ends in a triangular, pink tip with small black dots, the number of which increase with age.

Nocturnal ambush predators such as cats and snakes have vertical slit pupils helping them to judge the distance to prey in dim light. Different ambush predators use a variety of means to capture their prey, from the long sticky tongues of chameleons to the expanding mouths of frogfishes.
Báez and Rodriguez, initially signed to contracts by former general manager Al Avila in the 2021-22 offseason, will have to decide Nov. 6 whether to stay with the Tigers or become free agents.
