Do Salamanders Have Nostrils?

If you’ve ever spotted a salamander moving slowly through damp leaves or swimming in a cool stream, you might have wondered how it breathes. With such smooth skin and quiet movements, it’s natural to ask: do salamanders even have nostrils, or do they breathe some other way?

Yes, salamanders do have nostrils. These tiny openings sit near the tip of the snout, and while they’re easy to miss, they serve some important purposes.

Salamanders use them for smelling and, in some species, for breathing. But here’s the thing: their nostrils are only one piece of a much more interesting breathing system.

What Salamander Nostrils Look Like

Salamander nostrils are small and round, usually hard to spot unless you look closely.

Behind those little holes are nasal passages that connect to the mouth and play a role in both smell and air intake.

Still, nostrils aren’t the main way salamanders breathe.

In fact, even salamanders without lungs have nostrils, which tells us they serve another key purpose: helping with smell.

How Salamanders Use Their Nostrils

While salamanders can pull in some air through their nostrils, they mostly use them to detect scents. Their sense of smell is sharp, and it helps them survive in quiet, hidden environments.

When a salamander crawls across the forest floor or slips through shallow water, it picks up chemical cues through its nostrils. These signals tell it where food is, warn it of predators, and even help it find a mate.

So yes, salamanders can breathe a bit through their nostrils, especially if they have lungs. But breathing is not the nostrils’ main job.

Salamanders Have More Than One Way to Breathe

Here’s where salamanders get interesting: they don’t depend on just one organ for breathing. Instead, they mix and match several methods depending on their species and habitat. They can breathe through:

• Lungs (in some species)
• Skin, which absorbs oxygen directly
• Mouth and throat lining, which also allows gas exchange

These options let salamanders live in very different places (wet soil, running water, or the forest floor). Nostrils are just a small part of this bigger system.

Skin Breathing Is the Big One

The most important method for many salamanders is skin breathing, or cutaneous respiration. Their thin, moist skin lets oxygen pass straight into the blood.

This is why salamanders are almost always found in damp or wet environments.

Skin breathing even allows some salamanders to stay underwater or buried in wet soil for long periods without needing to surface.

But it only works if the environment stays moist. Dry conditions can quickly become dangerous.

Mouth and Throat Breathing

Another method is mouth-and-throat breathing. The soft lining inside these areas is packed with tiny blood vessels that soak up oxygen. This method usually helps when salamanders are resting or moving slowly.

Sometimes the nostrils play a small role here, pulling air into the mouth, but the real gas exchange happens in the soft tissues inside.

Not All Salamanders Breathe the Same Way

Because there are so many different salamander species, their breathing methods vary a lot.

• Aquatic salamanders may have gills and use little to no lung breathing.
• Terrestrial salamanders often have lungs and rely on nostrils a bit more.
• Lungless salamanders gave up lungs entirely, relying only on skin and mouth breathing.

But here’s the key: even lungless salamanders still have nostrils. That’s because nostrils are just as important for sensing the world as they are for air intake.

Nostrils as an Environmental Sensor

For salamanders, nostrils are more than just little air holes. They pick up smells from prey, predators, rivals, and even potential mates.

Chemical signals in the air help them know when to hunt, when to hide, or when to start courting.

In this way, nostrils give salamanders awareness of their surroundings, almost like a built-in radar system.

Conclusion

So, do salamanders have nostrils? Yes, they do. But unlike mammals, salamanders don’t depend on them as their main way of breathing.

Instead, they rely on skin breathing, mouth-and-throat breathing, and sometimes lungs.

The nostrils still play a vital role, especially in detecting scents that help salamanders survive in their hidden, often damp worlds.

They’re proof of how flexible and adaptable salamanders are, creatures that don’t just breathe one way, but several.
