Have you ever wondered why some sloths have two toes and others have three? Let’s dive into the fascinating world of sloths and find out more about these adorable creatures!
First, let’s clear up a common confusion: both two-toed and three-toed sloths actually have three toes on their back feet. The difference is in their fingers! Two-toed sloths have two fingers, while three-toed sloths have three. Millions of years ago, these sloths were part of the same species, but over time, they evolved into two different groups.
Long ago, there were giant sloths like the three-toed megatherium, which was as big as an elephant, and the two-toed megalonyx, known for its large claws. As time passed, sloths became smaller and spread across North and South America. This change helped them conserve energy since their diet mainly consists of leaves, which aren’t very nutritious. Moving slowly also helps them avoid predators like the Harpy Eagle, which prefers hunting two-toed sloths.
Two-toed sloths are larger, faster, and mostly active at night. They can rotate their heads 90 degrees. On the other hand, three-toed sloths are slower, more gentle, and can turn their heads a whopping 270 degrees! They can be active during the day or night.
Three-toed sloths are often seen as pets because they are cute and gentle. However, taking them from the wild can harm their natural populations. There are four types of three-toed sloths: Maned, Pale-Throated, Brown-Throated, and Pygmy. The Pygmy sloth is the smallest and lives only on a tiny island off the coast of Panama, making it endangered.
There are two species of two-toed sloths: Linnaeus’s and Hoffman’s. Linnaeus’s sloths have a large habitat and are good at hiding, which helps them survive. Hoffman’s sloths, however, sometimes wander onto farms where they can be in danger. They are also captured for the exotic pet trade.
Here’s a fun fact: the birth ratio of three-toed sloths is about equal between males and females, just like humans. But for two-toed sloths, there are about 11 females for every male! Female two-toed sloths often form small groups, while males prefer to be alone.
Sloths, whether two-toed or three-toed, are amazing creatures with a rich history. They are native to the Americas and have unique family lives. Which sloth do you find more interesting, the two-toed or the three-toed? Let us know what you think!
And remember, it’s Sloth Week! You can find more sloth videos on YouTube or by visiting SlothWeek.com. Enjoy learning more about these incredible animals!
Let’s play a game to remember the difference between two-toed and three-toed sloths! Use your fingers to show how many fingers each type of sloth has. Remember, it’s about the fingers, not the toes! Practice with a friend and quiz each other.
Create a timeline of sloth evolution. Start with the giant sloths like the megatherium and megalonyx, and show how they evolved into the smaller sloths we know today. Use drawings or cut-out pictures to make your timeline colorful and informative.
Build a diorama of a sloth’s habitat. Use a shoebox and materials like leaves, twigs, and clay to create a mini rainforest. Include both two-toed and three-toed sloths and show how they might hide from predators like the Harpy Eagle.
In groups, act out the behaviors of two-toed and three-toed sloths. One group can show the nocturnal activities of two-toed sloths, while another group can demonstrate the head-turning abilities of three-toed sloths. Share your role-plays with the class!
Create a poster to raise awareness about sloth conservation. Include facts about the endangered Pygmy sloth and the dangers of the exotic pet trade. Use drawings, slogans, and facts to make your poster eye-catching and informative.

There are two-toed sloths and three-toed sloths, but other than their toes, what’s the difference? Hello friends, I’m Trace, thanks for tuning in to DNews! As you’re likely aware, it’s SLOTH WEEK! Obviously, we’re all aware sloths are cute, slow-moving, and extremely photogenic, but let’s drill down a little further into these South American darlings.
Why do some sloths have two toes and some have three? Because of evolution. First, both two-toed and three-toed sloths have three actual toes. Yes, two-toed sloths have three toes, but only two fingers. About 35 to 40 million years ago, the two-toed and three-toed sloths were one species, but at some point, they mutated into these two distinct groups. The three-toed megatherium, or great beast, was the size of an elephant, and the two-toed megalonyx, or great claw.
As they evolved, the sloths shrank in size and spread through North and South America, likely to conserve energy, as leaves aren’t very nutritious. It could also be because movement attracts predators. A significant portion of the diet of Harpy Eagles consists of two-toed sloths, while a smaller percentage consists of three-toed sloths. You can probably guess which ones move more.
Two-toed sloths may move for several hours throughout the day, while some species of three-toed sloths may not move at all. In case you ever encounter a sloth, the two-toed ones are larger, faster, nocturnal, and can rotate their heads 90 degrees. The three-toed ones are slower and more docile, can rotate their heads 270 degrees, and can be either nocturnal or diurnal.
More importantly for you on the internet, three-toed sloths are more often seen as pets because they’re cute, don’t bite, and tend to be more docile. However, this doesn’t help their natural existence, as people keep taking them home. There are four species of three-toed sloth: the Maned, Pale-Throated, Brown-Throated, and Pygmy. The three-toed sloths have a blunter muzzle and simpler, peg-like teeth. The cutest of those is definitely the pygmy, which is quite small. It separated from the other three species almost 9,000 years ago and lives solely on Isla Escudo de Veraguas off the coast of Panama. Because it only lives in that one place, it’s definitely endangered.
The two-toed sloth is also really cute. It has a more defensive temperament and will defend itself. There are only two species of two-toed sloth: the Linnaeus’s and Hoffman’s. The Linnaeus’s sloth has a large habitat and a strong population due to its great camouflage and solitary nature, but the Hoffman’s sloth is often affected by its own cuteness. Its population is also strong, but the Hoffman’s tend to venture onto farmland where they can be harmed. They’re also hunted and captured for the exotic pet trade, again due to their cuteness.
Another big difference is that the three-toed sloth, like humans, has a sex ratio at birth of about 1-to-1 female-to-male. However, the two-toed sloth has an 11-to-1 ratio! When you spot a two-toed sloth in the wild, look for others, as the females form small groups while the males are solitary.
In the end, whether it be two or three toes, sloths are fascinating natives to the Americas with a rich history and complex family life. Which is your favorite, the two-toed or three-toed sloth?

Evolution – Evolution is the process by which different kinds of living organisms develop and change over long periods of time. – The long neck of the giraffe is a result of evolution, allowing it to reach leaves high in trees.
Adaptation – Adaptation is a change in a plant or animal that makes it better suited to its environment. – The thick fur of polar bears is an adaptation that helps them survive in cold climates.
Behavior – Behavior refers to the way an animal acts or responds to its environment. – The migration of birds to warmer regions during winter is a behavior that helps them find food.
Lifestyle – Lifestyle is the way in which an organism lives, including its habits and behaviors. – The nocturnal lifestyle of owls allows them to hunt for food at night when it’s cooler.
