Dolphins Jaws: 7 Facts you Should Know

Dolphins have an amazing set of teeths, but do they have jaws? This can be confusing because most other mammals need to move their jaws in order to grind up food that goes into their mouths. A dolphin’s skull has no moving parts, so how can they chew? Read below to know. 

Dolphins do have jaws but they do not have jaw muscles but they do have jaw bones.  The jaw of a dolphin is composed of bony elements which are connected with ligaments. The dolphin’s lower jaw extends in front of the upper jaw about as far as the nostrils, giving the jaw its characteristic shape.

 The answer lies in its lower jawbone. A dolphin’s lower jawbones have small muscular attachments that allow the dolphin to use these bones to slowly grind its food up after it swallows it whole or only partially chews it before swallowing it.

Now that you know dolphins do have jaws but do all of them have jaws? This has been a debatable question for a long time, since some people believe they do have while others are of the opinion they don’t. Let’s find out the truth. 

It might be surprising to learn that all dolphins have jaws. However, their jaws are very different from the ones of other animals. Dolphins do not chew their food like humans do; they swallow it whole and then use their tongue to squish it down in order to break it up enough to be digested properly in their stomachs.

Just like sharks, dolphins do have jaws. In some species of dolphin, such as the Bottlenose Dolphin, their jaws protrude outwards when open to accommodate a larger mouth. 

While this is not technically considered a jaw in the traditional sense, it does serve the dolphins very well in catching fish and other small prey.

Does Bottlenose Dolphins have Jaws?

 Bottlenose Dolphins are one of the largest animals on earth. In fact, the largest known species of dolphin can weigh around 5 tons and measure about 8 feet long. That’s enough to make most people believe that dolphins have jaws. But do they actually have teeth and jaws?

Bottlenose dolphins do have jaws. In Fact they have 18-26 small, sharp predator teeth on both the upper and lower jaws. Bottlenose dolphins also have several types of teeth that they use to chew their prey as well as several rows of peg like teeth in their mouth to help them swallow their food whole. 

The Bottlenose Dolphin is a carnivore, so of course they have jaws with teeth. In fact, they are one of the few aquatic mammal species that still has their full set of teeth, which can sometimes include a total of up to 50 in one individual Bottlenose Dolphin. 

These teeth often break or fall out, but they are continuously replaced through the various stages of the dolphin’s lifetime.

Do Dolphins have Jaw Muscles?

Do dolphins have jaw muscles? This can seem like an odd question at first since their faces don’t look like they have any muscles at all. There are various misconceptions around it. Let’s find out. 

Dolphins don’t have jaw muscles or facial muscles, but what they do have are several distinct anatomical features that allow them to effectively chew and swallow fish as well as manage the echolocation process which is vital to hunting and finding food in the water.

Just looking at the dolphin, you can see that there’s something different about its mouth; it has a jaw on each side of its head! This gives the animal much more flexibility when it comes to hunting and eating, but what does this mean exactly? Learn all about how dolphins use their jaws and why it’s considered such an important part of their lives.

Like having two ears on either side of your head, this physical feature gives the dolphin added protection against predators and an extra way to hunt prey and communicate with one another. 

It also helps these marine mammals hear sounds that are much lower and higher frequency than humans can hear, like dolphins using sonar to navigate the sea or whales talking to one another from far away.

Why is a Dolphins Lower Jaw Important

The lower jaw of a dolphin is not just important for the sake of aesthetics. It actually plays a vital role in their daily lifestyle. Let us take a look at why dolphins’ lower jaw is so important for them, and how you can use it too!

While the lower jaw of the dolphin was the primary pathway to the tympano periotic bone for returning acoustic signals during echolocation, it also has a secondary role that is equally important to dolphins’ unique ability to communicate through sound; connecting with other dolphins in the water and navigating their underwater environment effectively. 

The lower jaw of dolphins serves as an attachment point for numerous muscles that allow them to make vocalizations, such as clicks and whistles, as well as some muscles that aid them in using echolocation.


In a nutshell, With a jaw bone on each side of its head, a dolphin is able to use its jaws to grind fish, squid and crustaceans into a paste-like substance and then swallow it whole. In the dolphin’s stomach, this paste-like substance is separated from the water that makes up most of the dolphin’s food.
