How Many Species of Sloths Are There?

When you think of a sloth, you probably picture a sleepy, slow-moving creature hanging from a tree with a big, goofy smile. And while that image isn’t wrong, there’s more than one kind of sloth living the slow life in the treetops of Central and South America.

So how many species of sloths are there? 🧐

Let’s hang around and find out!

The Quick Answer (Ironically):

There are six living species of sloths, divided into two main types:

• Two-toed sloths (Genus: Choloepus)

• Three-toed sloths (Genus: Bradypus)

Yes, sloths are categorized by the number of toes on their front limbs not their back feet. (Weird, right?)

Let’s break them down:

Two-Toed Sloths (Genus: Choloepus)

These sloths are generally larger, more active at night (nocturnal), and have two toes (actually two fingers) on their front limbs.

There are 2 species of two-toed sloths:

1. Linnaeus’s Two-Toed Sloth (Choloepus didactylus)

   • Found in northern South America

   • Shaggy fur, pig-like snout

   • Often kept in zoos

2. Hoffmann’s Two-Toed Sloth (Choloepus hoffmanni)

   • Found from Honduras to northern South America

   • Slightly smaller range than Linnaeus's

   • Good climber and likes humid forests

Fun Fact: Two-toed sloths are actually faster than three-toed sloths… but that’s still not saying much.

Three-Toed Sloths (Genus: Bradypus)

These sloths have three toes (again fingers!) on their front limbs and are generally smaller and more sluggish than their two-toed cousins.

There are 4 species of three-toed sloths:

1. Brown-Throated Sloth (Bradypus variegatus)

   • Most common and widespread

   • Found from Honduras to northern Argentina

   • Recognizable by its brownish neck patch

2. Pale-Throated Sloth (Bradypus tridactylus)

   • Found in northern South America (Guianas and Venezuela)

   • Has a lighter-colored throat

3. Maned Sloth (Bradypus torquatus)

   • Lives only in the Atlantic Forest of Brazil

   • Has a thick “mane” of black fur

   • Endangered due to habitat loss

4. Pygmy Three-Toed Sloth (Bradypus pygmaeus)

   • Found only on Isla Escudo de Veraguas, a tiny island off Panama

   • Critically endangered

   • Much smaller than other sloths

Fun Fact: The pygmy three-toed sloth was only discovered in 2001!

Did You Know?

• Sloths may be slow on land, but they’re strong swimmers and can hold their breath for up to 40 minutes!

• They descend from trees only once a week… to poop. (Now that’s commitment.)

• Ancient giant sloths once roamed the Americas some as big as elephants!

Why It Matters

Of the six sloth species, two are threatened with extinction. Preserving their rainforest habitats and supporting conservation efforts is key to keeping these fascinating animals around and hanging out for generations to come.

Final Thoughts

So, to answer the question:
There are 6 species of sloths alive today 2 two-toed and 4 three-toed.

Each has its own unique charm, from the maned sloth’s shaggy “lion look” to the tiny, island-dwelling pygmy sloth.

They may be slow, but they’re worth learning about and protecting.
