Sloth Lapbook Information

Here are some sample lessons from the Sloth Lapbook:

Physical Characteristics of the Sloth:
Both males and females are the same in appearance. 

They are 21-29 inches long and weigh 9-19 pounds. 

Sloths have round, flat faces, small ears and big eyes. Their nose is flat and round, resembling a pig’s snout.

There are 2 curved claws on the front legs of the two-toed sloth and 3 on the front legs of the three-toed Sloth. Both two and three- toed sloths have 3 claws on their hind legs. Their claws are 3-4 inches in length and are used to grasp tree limbs as they climb. The legs of the three-toed sloth are longer than the rear ones. The legs of the two-toed sloth are more similarly sized. The front limbs are very strong. 

Three-toed sloths have a small tail. The two-toed sloth does not have a tail at all. 

Sloths have dense, shaggy hair. Unlike the hair of other mammals that grows from the back down towards the belly, the sloth’s hair grows from the belly towards the back. This is uniquely suited to their upside down lifestyle and allows the rain water to run off. This top layer of hair is long, very coarse, and grooved. It is brown or gray in color. During the rainy season, they turn a greenish color due to algae living in the groove of their hair. Beneath this top layer of coarse hair is a layer of downy hair that helps to protect the sloth from insects.

Sloths make a long, high-pitched sound. It sounds like aaaaa-eeeee.

Sloth Anatomy:
The sloth has a long tongue, large peg-like teeth and hard, tough lips. It uses its tongue to tug on food and pull it to their mouth. It then tears the food with its lips and grinds it with its teeth. 

The sloth’s body temperature is the lowest of all mammals, at 93 degrees. It fluctuates with the temperature of its environment like that of a cold-blooded creature such as a snake. Its body temperature can fluctuate as much as 10 degrees in one day. If our temperature fluctuates even just 5 degrees, it is life threatening. 

The stomach of a sloth is compartmentalized, like that of a cow. (See Diet for more information).

Vertebrae are the bones that form the spine. The three-toed sloth has nine neck vertebrae while the two-toed sloth only has six or seven. Most mammals have seven. The extra neck vertebrae of the three-toed sloth allow it to turn its head farther to the right and left than any other mammal. 

Sloths are extremely slow due to the anatomy of their limbs. They are unable to stand on their rear legs and walk like most mammals. When on the ground, they must pull themselves slowly along with their front limbs. They are strong climbers and swimmers. When swimming, they use an overarm stroke with their strong front limbs. 

Because sloths are so inactive, their muscle mass is much less than that of other mammals. This explains their lower weight and also makes it easier for them to climb on thin branches in the canopy where they can hide more easily.
