Three Toed Sloth

By: Nolan Faselt


Why This Animal?

I was interested on the Three Toed Sloth cause when I was little I was at a zoo and I was looking into a cage and it creped down from the tree right in front of me and scared me. Also I heard that sloths do nothing and I wanted to find out what they really do. The Sloth is a very interesting animal and I wanted to find out if it had any close relations (because most other animal do). This animal wouldn’t be fast enough to attack another animal for food so I wanted to know what they eat. Also I kind of wanted to have a pet Sloth since I was little and I always wonder how they act around others if there protective or kind. This is why I me researching the Three Toed Sloth.

Rainforest is the biome that the Three Toed Sloth lives in. The Three Toed Sloth wouldnt be able to live in anyothertype of biome casue it wouldnt be able to stay in the trees. Some of the other biomes dont even have trees and the Sloth wouldn't be able to out run the preditors. So it lives in the Rainforest so it can stay away from its preditors. This biome helps them alot cause all the trees are so close so the rarley have to climb down to go to a diffrent tree. These trees have many branches for the Sloths to climb around on. Such as Capirona Tree and Buttress Root Tree cause they are the easiest to move around on for the sloths.


The biome is the rainforest it has many different animals and plants. Some of the animals range from Sloths and monkeys to snakes and birds. This rainforest that the Three Toed Sloth lives in has about 50 – 260 inches of precipitation a year. This Rainforest has temps in a range of 68 - 93°F. This amount of rain helps all the plants in the region to live. Since there are so many plants in the rainforest there needs to be lots of precipitation for all the plants to grow. If there wasn’t that much precipitation then their wouldn’t be as many plants. Rainforest is a very nice place for the animals that live there to case of the many plants for them to hide behind.

Also plants can provide food and shelter for the Three Toed Sloth. The rainforest is the best place for the Three Toed Sloth to live cause of its many close trees. Also the rainforest is very dens and green for them to hide form predators. The Sloths cant live in very many other biomes but the rainforest is its best chance to survive from predators. The rainforest area is going down so is the sloth population. Farmers want more farming land so they cut down all the to plant their craps. This causes the homes of the Sloths to be destroyed.

My Journal

Day 1

Today when I was walking around searching very hard to see the Three Toed Sloth. This animal is very hard to find cause of fur that helps it hid in the brush of the trees. Also most other animals are active and you can see or hear them moving around. The Three Toed Sloth doesn’t move very often and trys to stay hidden from preditors.

Once I found the Three Toed Sloth it was easy to observate and watch. It used it huge claws to get a strong furm grip on the tree branches. Also its arms and legs are made to hang and swing from the branches. The Three Toed Sloth’s body has adapted to a life within the trees. It has a loose and flexible body to move around and up the branches. Also a Three Toed Sloth can rotate its neck almost all the way around to see preditors, food or other opsticles.

Day 2

The next day I went back to the spot of where I saw the sloth and it had moved….. to the next tree over. The sloth was climbing down the tree to a patch of fruit hanging. The sloth examined the fruit very carefully and then ate it. It was being very gracefuly climbed and swung very slow threw the trees. Just a couple of trees down I saw another sloth so I went over to it. The Sloth had a baby hanging to it. The baby sloth was trying hard to hold on to the mothers back.


Monitoring Technigue

To trace where the Three Toed Sloth has been I think that a radio tower and collar would work the best. A motion censored camera would only have been good if the sloth kept going back and forth through that one tree. Even if the sloth moves through that tree its slow and wouldn’t do it often so the camera wouldn’t get very many pictures. So I think that the collar would help the researchers find out about where and when sloths move around. Also if we had the towers we wouldn’t have to have it covering a huge area of land because the sloth does not travel very far. It would be the best way to track Three Toed Sloths.

Bryson Voiron

Bryson and I are some what alike we both love and have many questions about Three Toed Sloths. The only thing that is different is Bryson is from the Max Planck institute in Germany. He is working now at the Smithsonian Tropical Research Institute in Panama. Bryson’s lab is study animals sleep but his study is based on the sleep of Three Toed Sloths and I’m studying the Three Toed Sloth for my science showcase.

One of the easiest animals to research cause they sleep most of the day and are very easy to catch not traps or nets slowest mammal But very hard to spot it though. It’s very hard to find the Three Toed Sloth in the trees because the sloths life is to hide from all other animal and not react to any movement or noise.

Bryson has noticed that the sleep of the Three Toed Sloth varies in the wild sleeps less than the Three Toed Sloths in captivity. The Three Toed Sloth Bryson has watched in the wild slept for an average of 9.5 hours. He has also averaged the Three Toed Sloth in captivity and it sleeps an average of 16 hours. Bryson thinks it’s the diets that the sloth eats which affects it brain waves and how long it sleeps. Another reason the researcher thinks sloths in the wild sleep less is cause of its predators.
