They have a bill and a tongue, but no teeth. First of all, penguins have a beak, with a pointy end to help them to grab their food, typically fish. The other outstanding feature of their mouth is the spikes on their tongues and the rooves of their mouths, that look like stalagmites and stalactites in a cave.
Those teeth-looking structures on the tongue and palate are actually comprised of soft keratin spikes called papillae. They appear sharp on the top, and curve backwards toward the back of the mouth.
Like other birds, penguins don't have teeth. Instead, they have backward-facing fleshy spines that line the inside of their mouths. These help them guide their fishy meals down their throat.
Even if they attack, penguins aren't large or strong enough to severely harm an adult human. And they do not need to! There has also never been a recorded penguin-related death. Although this is true, scientists and researchers have reported bites and hits while handling penguins.
A penguin's tongue, though lacking taste buds, has large keratinized bristles that help grip the krill or fish as it enters the mouth.

Penguins use the two-voice system to recognize each other.
It comes out their nose in super salty tears! So, penguins do sort of cry, but from their nose not their eyes.
During aggressive encounters, around 70 percent of penguins showed lefty tendencies, bloodying the right side of an opponent. “They hit, they bite, they peck,” explains Rebstock, who has personal experience with such encounters. “These penguins can do some damage. I've been whacked.
It should really go without saying, but you cannot go around touching the penguins. Penguins are tiny birds that are susceptible to human interference, and the last thing they want are some annoying touros getting down into their nests and trying to pick them up.
WILD FACTS 278043: Penguins pee A LOT. So much, in fact, that nearly three percent of Antarctic glacier ice is made up of penguin urine!
Summary: Although flightless in air, penguins have a number of adaptations which allow them glide effortlessly through the water. And some of these adaptations are in an unlikely part of their anatomy -- their brains.
You Can't Hug the Penguins
These minimum distance rules avoid causing birds and seals any concern or distress. Moving quietly and slowly is the best way to take in the splendour of your surroundings while observing these amazing creatures as they go about their daily business.
The sharpest teeth of any animal belong to the conodont (Conodonta) class of eel-like vertebrates that evolved ca. 500 million years ago in the Precambrian eon. Despite being jawless, conodonts had teeth with tips as small as 2 micrometres across (1/20th the width of a human hair).
Big cats such as lions, tigers and cheetahs have some of the sharpest canine teeth in the animal kingdom. These long, dagger-like weapons are used to stab – biting down deeply into the throats of prey to bring them down.
THE SHARPEST TEETH EVER discovered belong to a surprising animal: a jawless, eel-like vertebrate that lived from 500-200 million years ago. Scientists suspect the conodont was one of the first vertebrates ever to develop teeth.
Yes, penguins also have feelings, and they can feel a range of emotions and even have a way to communicate them. Penguins use six distinctive vocal calls to express their emotions and feelings. African penguins can express loneliness, hunger, and irritation.
They're super friendly with people.
Penguins' main predators (seals, sea lions, whales, and sharks) all reside in the water, so these birds feel much safer on land around researchers and tourists — for better or for worse.
The study, led by Dr Livio Favaro, found that adult penguins produce distinctive short calls to express their isolation from groups or their mates, known as "contact" calls, or to show aggression during fights or confrontations, known as "agonistic" calls.
Male penguins give their partner thoughtful gifts, but they also express their love physically. Penguins often dance for joy at the sight of someone they love. When penguins find their love, they also sing to them.
Like crows, which can remember particular human faces for years, many penguin species have remarkable memories.
Last year's coverage of the grieving orca mother is a prime example of popular culture's slow recognition that animals of all kinds grieve their dead. Between March of the Penguins and the present suffering of emperor penguins, I have come to learn that grief is a part of life, all life.
They can sleep either lying down or standing up on the rocks and sometimes when they are standing up they will tuck the beak under the wings.
Penguins are fascinating creatures, not just because of their physical characteristics. They're amazing at creating mental maps, can recognize each other's calls, and hunt in a coordinated way. Penguins might not be the smartest animal on our list, but they're pretty incredible in their own way.
Well in short – yes, penguins do have knees (well that was pretty anti-climactic). A penguin's legs are built up of a femur, knee, tibia and fibula, just like yours. Their legs may appear short and stubby, but don't be deceived, most of them are concealed by feathers.
