what do emperor penguins eat

The Emperor penguin (Aptenodytes forsteri) is renowned not only for its stature as the tallest and heaviest of all living penguin species but also for its unique dietary habits in the harsh Antarctic environment. As a species that has adapted to one of the world’s most extreme habitats, understanding “What Do Emperor Penguins Eat?” is crucial to appreciating how they thrive in such a cold, remote place.

What Do Emperor Penguins Eat?

Primarily, Emperor penguins are carnivores, focusing their diet on the rich marine life available in the Southern Ocean. Their eating habits are specialized to the availability of prey within the icy waters surrounding Antarctica. Here’s a closer look at the specifics of their diet:

Main Food Sources

  • Fish: Emperor penguins often consume a variety of fish which are abundant in the Antarctic waters. These fish are rich in fats, which are essential for insulation in the cold climate.

  • Krill: Another significant component of their diet is krill. These small crustaceans are not only a plentiful resource in Antarctic waters but also a critical part of the marine food chain.

  • Squid: Squid provide another source of protein and fats for Emperor penguins. Their ability to catch these quick, agile creatures showcases the penguins’ prowess as skilled swimmers.

Foraging and Feeding Behavior

Foraging and Feeding Behavior

Emperor penguins are exceptional swimmers, a trait that is essential for their survival and efficiency in hunting. They can dive deep and stay underwater for more than 15 minutes at a time while searching for food. Their streamlined bodies and powerful flippers allow them to navigate swiftly through the water, catching prey with precision.

Adaptations to a Harsh Environment

  • Social Foraging: These birds often hunt in groups, which increases their efficiency in finding and catching prey. This social aspect of foraging also helps them protect each other from potential predators.

  • Fat Storage: The high fat content in their diet is crucial not only for insulation but also for energy storage, which is particularly important during the breeding season when food may be scarce.

Emperor Penguin Lifespan

Emperor penguins have a lifespan of typically around 20 years in the wild, although some individuals have been known to live up to 50 years. This longevity is remarkable, considering the extreme weather conditions of their Antarctic habitat. Factors contributing to their lifespan include their robust adaptations to the cold, their social structures that help mitigate the risks from predators, and the abundance of food in their marine environment.

Where Do Emperor Penguins Live?

Where Do Emperor Penguins Live

Emperor penguins are endemic to Antarctica, residing along its coasts and on the surrounding ice. They are particularly tied to regions where ice cliffs and icebergs provide some shelter from the harsh Antarctic winds. During breeding season, they are found on stable pack ice near the coast, where they form large colonies that can number in the thousands. These locations provide relatively stable conditions for laying eggs and raising chicks despite the extreme cold and wind.

Do Penguins Have Teeth?

Penguins do not have teeth as mammals do. Instead, they have backward-facing soft spikes inside their mouths. These spines are not teeth but are similar to denticles that help them grip and guide fish down their throats. This adaptation is crucial for their survival, allowing them to catch slippery prey like fish and squid effectively.

How Many Teeth Do Penguins Have?

Since penguins do not have true teeth, they do not have a countable number of teeth like humans or other animals. Instead, their mouths are lined with numerous small, spine-like projections. These projections vary in size and density depending on the species of penguin, but they all serve the same purpose of helping the penguin secure its food when it catches it. The precise number of these spines can vary, but their arrangement is designed to be incredibly effective for a carnivorous lifestyle in a challenging marine environment.


Understanding what do emperor penguins eat allows us to glimpse into their complex lives beneath the ice of Antarctica. These majestic birds have adapted their diet and foraging techniques to not only survive but thrive in one of the most extreme environments on Earth. Their ability to exploit the ocean’s resources around them is key to their survival, making the Emperor penguin a fascinating subject for studies on adaptation and survival. By protecting their environment, we help ensure that these incredible birds continue to march across the icy landscapes for generations to come.
