Why do lemurs have big eyes?
All members of the family Dwarf lemurs belong to nocturnal animals that are active only with the onset of the dark time of day, which is why large eyes are caused, which see well at night thanks to special light reflecting crystals. In the daytime, such mammals sleep, characteristically curling up in the ball.

You may be wondering “Why do lemurs have long noses?”
Lemurs have long noses that help them smell. Many species of lemur are endangered, which means there aren’t many of them left and they’re in danger of going extinct . The main reason lemurs are endangered is that humans are destroying the forests where they live–people cut down trees for the wood or to make room to grow crops.
Do lemurs have color vision?
Since cone cells make color vision possible, the high prevalence of rod cells in lemur eyes suggest they have not evolved color vision. The most studied lemur, the ring-tailed lemur, has been shown to have blue-yellow vision, but lacks the ability to distinguish red and green hues.
Then, what kind of lemur is blue eyed black?
For example, blue-eyed black lemur males are solid black while the females are reddish-brown. The lemur species that are diurnal are social and live in family groups or troops. They follow the safety-in-numbers idea, using alarm calls when a predator is spotted to inform the rest of the group.
Then, what kind of primates have blue eyes?
Other than humans, the only primates with naturally occurring blue eyes are the blue-eyed black lemurs, sometimes called Sclater’s lemurs. The blue-eyed black lemur is one of the most threatened lemur species, listed as Critically Endangered on the IUCN Red List of threatened species (6).
What does a lemur look like?
Lemurs have a slender frame, a narrow face that is white with black patches around the eyes and a black fox-like muzzle. The lemur can easily be recognised by its long, bushy tail that is ringed with twenty six black and white rings.
This of course begs the query “What does a lemur look like with a white tail?”
By far the most recognizable species is the ring-tailed lemur. Named for its ringed black and white tail, these lemurs have black skin, wide brown eyes, and gray coats. The lesser mouse lemur, or gray mouse lemur, has reddish-grey fur and, as the name suggests, looks a bit like a mouse.
Their faces are white with dark triangular eye patches and a black nose. True to their name, ring-tailed lemurs’ tails are ringed with 13 alternating black and white bands. Unlike most other lemurs, ringtails spend 40 percent of their time on the ground.
