Sloth is a arboreal mammal known for its slow motion and most of the time hanging upside down in the tropical rainforests of South and Central America. These six species have two families: two toed sloth and three toed sloth. Despite this traditional nomenclature, all sloths actually have three toes. The two toed sloth has two numbers or fingers on each forelimb.
Laziness is so named because its metabolism is very low and its exercise is deliberate. Laziness is related to the word "slow". This is an evolutionary adaptation to a low-energy leaf diet and avoids predatory hawks and cats that are prey to the naked eye. Laziness is almost helpless on the ground, but it can swim. The fluted hair on the slothful furry coat is the host of symbiotic green algae, which helps the sloth camouflage itself in the tree and provides nutrition for the sloth. Instead, algae nourish sloths, some of which are only found on them.
They are classified into pilosa in the order of anteater. Extinct sloth species include ground sloths of many giant fungi, some of which reach elephant size, as well as marine sloths.
The common ancestor of the two genera can be traced back to about 40 million years ago, and the similarity between two toed and three toed sloths is an example of fusion evolution.
Ancient xenarthra has a lot more species than today. In ancient times, sloth was not a arboreal animal, but lived on land, similar in size to bear. Megatherium, a widely distributed species, is bigger than elephants.
Swimming is believed to have led to the spread of the peluscan sea of the Caribbean to the Antilles in the Oligocene, and pliometanastes of the Crocodilidae and thinobadistes of the canines were able to settle in North America about 9 million years ago, long before the isthmus of the isthmus existed. Panama. In addition, the non animal thalassocnus on the west coast of South America adapted to the semi aquatic marine lifestyle.
In Peru and Chile, the thalassocnus sloth adapted to the coastal marine lifestyle that began in the late Miocene. At first they just stood in the water, but in four million years, they eventually evolved into swimming creatures.
Baby sloths learn to eat by licking their mother's lips. All sloths eat the leaves of the cecum.
The two toed sloth diet includes insects, carrion, fruits, leaves and small lizards, covering an area of more than 140 hectares. On the other hand, only a few trees in the diet of the three toed sloth have limited leaves, and no mammal can digest them as slowly as this.
They have adapted to tree browsing. Leaves are their main source of food. They provide little energy or nutrition and are not easy to digest. Therefore, the sloth's stomach is large and its movement is slow. There are multiple compartments. Symbiotic bacteria can decompose tough leaves. Two thirds of a well fed sloth's body weight is made up of the contents of its stomach, which may take a month or more to digest.
The three toed sloth urinates and defecates about once a week, digs a hole, and then covers it. They go to the same place every time, and are easily plundered in doing so. This may be related to the maintenance of the ecosystem in the sloth fur. Sloths spend most of their time on a single "modal" tree. By burying the waste near the trunk of the tree, they can help nourish it. Recent studies have shown that moths living in sloth fur lay their eggs in sloth dung. When they hatch, the larvae feed on manure, and when they mature, they fly to the sloth above.
