Lemurs (Lemur), living in the eastern region of Madagascar, are mammals with echolocation capabilities. Madagascar in Africa is the last sanctuary for lemurs, a primate with beautiful big eyes that has disappeared from the rest of the planet except this island.

Lemuridea has 26 species in 8 genera. This is the most primitive primate. The skull and nasal bones are elongated and shaped like a fox. Tooth type: 0～2/2, 1/1, 3/3. 3/3=32～36, the upper incisors are small or absent, there is a wide void between the incisors on both sides; the lower canines are cut, the first The lower premolars are canine-shaped and the molars are basically tricuspids. The sagittal ridge at the origin of the temporalis muscle is inconspicuous. The thumb and the big toe are somewhat enlarged, and are opposite to the other fingers and toes, and the second toe has a hook. The tail is long and hairy. Diverse diets, diurnal or nocturnal, are sensitive climbers.

Lemurs have a longer history and more species than previously thought. Ancient primates: Fossils of the 35-million-year-old primate Wadilemur elegans suggest that lemurs originated much earlier than old fossil evidence suggests. Lemurs are small primates endemic to Madagascar. A new fossil discovered by scientists in Egypt suggests that lemurs and other primates appeared much earlier in evolutionary history than previously thought; in addition, scientists have discovered five new lemur species.

Lemurs are primates The generic name for the Prosimian suborder Lemuridae. The body size varies greatly, and the appearance is similar to that of mice, cats, foxes and monkeys. Body length 13 to 60 cm. Weight 60-3000 grams; tail length 17-60 cm, equal to or exceeding body length, with dense and long tail hair, mostly broom-shaped; large eyes; , shaped like a fox's mouth; the outer ear shell is semicircular or densely haired; the hind limbs are longer than the forelimbs, the fingers and toes have flat fingernails, and the second toe of the smaller species has grooved and curved claws; 36 teeth, only Weasel lemurs have 32 teeth, missing the upper incisors. Lemurs living in Madagascar and the Comoro Islands have elongated bodies with thick, soft fur in a variety of colors and markings. Most lemurs are reddish, brown, grey and black. The ring-tailed lemur, or Madagascar cat, has a grey-brown back with black and white rings on its tail. The fork-marked lemur is reddish or taupe, with black stripes from the eyes to the top of the head, which meet and extend toward the back as a stripe. The great weasel lemur (greater weasel lemur) is brown or grey on the back and white or yellow on the belly.

Lemurs come in a variety of sizes. The smallest lemurs are the dwarf lemurs (dwarf lemurs) and the mouse lemurs (mouse lemurs), which are only about 5 inches (13 cm) long, and the largest is the collared lemur (ruffed lemur), which is about 24 inches (60 cm) long . Other large lemurs are brown and gentle lemurs. Body length 14 to 18 inches (34 to 45 cm). (All body lengths given for lemurs refer to the trunk only, and the tail of lemurs is as long as the trunk or even longer than the trunk.) Lemurs have fingers (toes) on both their fingers and toes (except the second toe). nails, and claws on the second toe. Some lemurs have raised pads on the palms and soles of their feet, and some also have pads under the fingers and toes. Some lemurs have a fox-like face, short muzzle, and large eyes that are narrowly spaced apart.

Lemurs are the most primitive monkeys. Although its body shape, hands and feet are like monkeys, its face is like a fox and a dog. The segment-tailed lemur, also known as the ring-tailed lemur, is a primate, Lemur family, Lemur Catta, scientific name Lemur Catta, no subspecies. They have a beautiful long tail with black and white links. They like to bask in the sun, and they arch their backs, much like a squirrel , reach out and enjoy the warmth of the sun. It turns out that they are very afraid of the cold, and often a few gather their tails around themselves and their companions, and it is impossible to tell which tail belongs to which one. They are mild-mannered and clean, and use their claws for grooming and grooming every day. For a segment-tailed lemur, being born a male is doomed to be a "second-class citizen" all its life. In the festival-tailed lemur society, "the supremacy of women and children" is a law that cannot be violated. From another point of view, the segment-tailed lemur is also unusual. They belong to the order of primates, one of the direct ancestors of humans.

The smallest species of lemur is called the "mouse lemur", and some are only a few inches long. They are used to living in trees and are active at night. In the dry and hot season, mouse lemurs sleep for a long time and don’t eat for a few weeks. However, before sleeping for a long time, they should eat as much as possible to store up fat, and then slowly absorb it into the body when they are on a hunger strike. Go to the various ministries and organizations to maintain life.

The least common of the lemurs is a tarsier, which is about the size of a mouse. They live in bamboo forests and live a night life. A long tail is bare except for a tuft of hair at the tip of the tail. The eyes are very big, and the round ones seem to be wearing a pair of glasses, so they are called "tarsier monkeys". Disc-like things grow on its fingers and toes, so it can crawl on slippery surfaces.

In this class of extremely low-level monkeys, there is also a species called Pinus monkeys. It lives in the dense forests of Madagascar. They eat insects

especially like to eat sugarcane juice. They are often seen in sugarcane fields at night. The fingers of the piny-fingered monkey are extremely thin, especially the middle finger, which is only as thick as monkey silk. Such slender fingers can be useful, and can dig insects out of small holes in the bark to eat. I also eat eggs and hard nut shells. When I eat them, I bite them open with my teeth, hold them with one hand, and then use this very thin finger to go in and dig out the contents to eat. The speed of digging is extremely fast. .

In addition, the weasel lemurs produced near Madagascar are smaller than ordinary lemurs, with a body length of about 25 cm and a tail that is the same length as the body. Big eyes, naked nose, brown body hair. The northern species is gray in color; the southern species is lighter; the two species on the east bank are darker in color and larger in size, with a body length of about 30 cm and a slightly shorter tail. Weasel lemurs have a special digestive system that allows them to re-eat their feces and absorb their nutrients in the cecum. This "cecal-absorbing" animal is extremely rare in primates. Weasel lemurs are nocturnal monkeys (with the exception of Nosypi weasel lemurs). During the day, when the weather is very hot, they sleep in the shade of tree ledges and branches, and come out to feed at night. Different from most nocturnal animals, weasel lemurs do not eat animal food such as insects, but mainly eat leaves, flower buds and other plants.
