If you ever get a chance to look inside a penguin’s mouth, you might be surprised at what you see. Imagine lots of hooked, barbed fish being swallowed by a penguin’s throat. The roof of their mouth is covered in rows of fleshy spines called papillae that bend inward towards their throat.
What Does a Penguin’s Beak Look Like?
Penguins also use their beaks to preen their feathers and catch food, helping them in fights with other penguins or predators. Their curved beak is mainly helpful for catching prey while swimming and diving into the water. Penguins do not have paws or hands, so their beaks are particularly handy. The sharpness, size, and color of their beaks vary depending on the species, and they are made of hard keratin. Penguins have two nares located on either side of their closed beak, which allow them to secrete salt and breathe. The hooked and sharp beaks are one of the defining features of penguins.
What do Penguins Eat?
Shrimp, also known as tiny crustaceans, resemble krill and squid. In addition to other small ocean creatures, shrimp are also consumed by penguins. They primarily consume smaller fish of all types, making up the majority of a penguin’s diet. Penguins are carnivorous animals.
The diet of penguins will greatly vary based on their size and geographical location. There are 18 different species of penguins, which exhibit a size range of 16 to 45 inches and a weight range of two to 82 pounds.

Inside a Penguin’s Mouth
Penguins have specialized papillae on the roof of their mouth and on their tongue, which allow them to guide and grasp their food as they chew and swallow. Instead of teeth, they have fleshy ridges that bend inward so that they can swallow whole prey, including fish.
Do Penguins Have a Tongue?
Imagine yourself in a cave, where you can see stalactites and stalagmites. The spikes on the roof of their mouth resemble a penguin’s tongue, don’t they?
Are There Teeth Inside a Penguin’s Mouth?
Penguins, like other birds, do not have teeth. They have what is known as an egg-tooth, which they use before hatching to break out of the shell. This little protuberance on their beak is quite handy in helping them break the shell. Additionally, the papillae in their throat allow them to guide food down and get a good grip on it.
Do Penguins Chew their Food?
Penguins don’t have teeth, so they don’t chew their food. Instead, they swallow pebbles or stones, which help to break down the food in their stomach. These pebbles or stones may eventually move or dissolve through their digestive tract. Swallowing fish whole is the answer to how they’re able to digest it. You may wonder how penguins push the food down their throat without spiky papillae.
Why Do Penguins Shake their Head When They Eat?
The salt derived from the water strains the supraorbital glands on both sides of the beak situated above the eye. These glands absorb a considerable quantity of saltwater while penguins feed.
If penguins were unable to do this, they would suffer from dehydration due to consuming excessive amounts of saltwater. When a penguin shakes its head or sneezes, it is expelling salt from that gland.
How do Baby Penguins Eat?
The baby penguins, also known as nestlings or chicks, rely completely on the food that their parents must transform into a suitable form for them to eat. Unlike adult penguins, the baby penguins cannot digest adult food. This reliance on their parents’ food is crucial for the first few months of their lives.
Once they reach the age of six or five months, they become independent. The nestlings are shown how to eat pebbles and catch their own food. The nestlings are shown how to eat pebbles and catch their own food. When they return to their chick, they directly regurgitate it into the baby’s beak. The parent will partially digest the food and swallow it in a few hours.
Are Their Taste Buds Inside a Penguin’s Mouth?
Most vertebrates can detect five basic qualities of taste. Studies show that even penguins, which have fewer taste buds, are unable to detect flavors or bitterness and lack the gene receptors for sweetness, unlike most birds. It leaves them with the ability to distinguish sourness and saltiness.
However, penguins have evolved to find bitter and umami tastes suggested to be sweet, considering that they typically swallow their food whole without tasting it much. This is because they live in the coldest environments where taste receptors cannot function properly.
