Question

the scleral ring and the orbit dimensions have a large impact on how animals have nocturnal behavior. What are some other traits that correlate to nocturnality

Answer 1

The investigation by one group of scientist indicates that the nocturnal have large internal sclera ring diameter in their eye for a given orbit depth compared to the diurnal’s eye. Apart from the sclera ring and orbit, it was reported that nocturnal possess a relatively larger cornea concerning their size of eyeball compared to the cornea of the diurnal’s eyes. The retina of the nocturnal’s eye is entirely composed of rod cells. They have the specialized pupils to protect their eye from the damaging bright light. Many nocturnal animals possess split pupils and tapetum lucidum (eyeshine).
