Penguins are flightless seabirds, a group of aquatic flightless birds that make up the scientific order Sphenisciformes and the family Spheniscidae. They live exclusively in the Southern Hemisphere, and the Galápagos penguin is only one species, found north of the equator. The tallest penguin is the Emperor penguin more than 1m in height, whereas the smallest penguin is the Galapagos penguin whose height is 49 – 53 cm. Penguins are highly adapted for life in the water and they have counter-shaded dark, white plumage and flippers for swimming.

Species of Penguins

There are 18 species of penguin, each of which is slightly different. All species live in the Southern Hemisphere. Many live in the South Pole of Antarctica. Some can be found on the coasts of Australia, Africa, New Zealand, South America, and the Galapagos Islands. There can be up to 100 million penguins around the globe.

• • Adelie Penguins – Adélie penguins from Antarctica have white circles around their eyes.
  • Humboldt Penguins – The Humboldt penguins are native to the coastal areas of Chile and Peru.
  • Chinstrap Penguins – Chinstrap penguins can build their nests during their reproductive period.
  • Magellanic Penguins – Magellanic penguins are natives of Argentina and Chile.
  • Northern Rockhopper Penguins – Northern rockhopper penguins are native to the southern Indian and Atlantic Oceans. Approximately 85 percent of the Northern Rockhopper Penguins are found in the South Atlantic Ocean and the remaining 15 percent is found in the Indian Ocean on Amsterdam and St. Paul islands.
  • Southern Rockhopper Penguins – Southern rockhopper penguins are native to some parts of South America and have short beaks and red eyes. Southern rockhoppers are smaller than northern rockhoppers. The average lifespan is about 10 years.
  • Emperor Penguins – Emperor penguins are the tallest penguins at more than 1m in height. They can sink in deep water in Antarctica.
  • Galapagos Penguin – The Galapagos Penguin is the smallest South American penguin that lives north of the equator
  • African Penguins – African penguins or Jackass Penguins originate from warm places such as South Africa and some parts of the coastal areas of Namibia.
  • Royal Penguins – Royal penguins are natives from some parts of Australia and have a full white face.
  • Gentoo Penguins – Gentoo penguins have white stripes around their eyes towards their heads.
  • King Penguins – King penguins have strong and bright colors on their chest, head, and back.
  • Snares Penguins – Senior penguins live on the New Zealand island of Snares.
  • Little Blue Penguins – The little blue penguins are the smallest type of penguins with a height of 13 inches.
  • Fiordland Penguins – Fiordland penguins are native to Fiordland, New Zealand, and have white spots on their beaks.
  • Erect-Crested Penguins – Erect-crested penguins come from the Antipodes and Bounty Islands.
  • Macaroni Penguins – Macaroni penguins are orange-yellow plum penguins.
  • Yellow-Eyed Penguins – The yellow-eyed penguins are native to New Zealand and have a golden yellow, spotted color around their eyes.

Penguin Facts & Information

• • The name “Penguin” comes from the Welsh, “Pen”, which means head, and “Gwyn”, which means white.
  • Penguin babies, called “chicks” or “nestlings.”
  • A group of baby penguins is called “crèche.”
  • Penguins mate for life.
  • Penguins are birds that can’t fly.
  • Penguins don’t live near freshwater.
  • There can be up to 100 million penguins in the world.
  • They spend half of their lives on land and half in the oceans.
  • There are 18 species of penguin, each of which is slightly different. All of the species live in the Southern hemisphere. Most of life was at the South Pole in Antarctica. Some can be found on the coasts of Australia, Africa, New Zealand, South America, and the Galapagos Islands.
  • Some penguins, such as the Galapagos penguins, manage to settle in warm temperatures.
  • Penguins have white and black feathers, when they walk they are waddled.
  • They’re from the scientific order “Sphenisciformes” and the family “Spheniscidae”.
  • Penguins are warm-blooded and have a normal body temperature of around 37 °C (100 °F).
  • The penguin can hold its breath underwater for about 6 minutes.
  • Penguins don’t live near freshwater, at least anything that isn’t frozen. Instead, they drink salt water.
  • Penguins rub oil from a gland on their feathers to help make them windproof as well as waterproof.
  • To keep each other warm, groups of penguins huddled each other shoulder to shoulder and strengthened their body wings. Up to 5,000 penguins will connect to warm each other up.

• • When the baby penguin hatches, it immediately begins calling for its parents to recognize its voice.
  • All the baby penguins in the colony will remain together until their parents return. When the parents return home, they recognize their chick again by the sound of its voice.
  • Penguins are very strong birds that can fly into the air at a height of 6 feet.
  • Penguins spend most of their time in the water looking for food.
  • Some penguins travel from 15 to 900 km in search of food.
  • They’re in the water at home when they dive, jump, play, spin, and search for food.
  • Penguins eat seafood. Their main diet is fish, but they also eat squid, small shrimp known as “krill” and crustaceans.
  • Under the skin of penguins, there is a layer of fat like whales called “blubber”.
  • Penguins have torpedo-shaped bodies. This shape allows them to go through water at a speed of 40 kilometers (25 miles) per hour. However, they can’t swim backward.
  • During the mating season, penguins move to special nesting areas on the shore. The area where penguins together, nest and raise their chicks is known as a rookery.
  • The penguins will build their nests with everything available, even stones and rocks.
  • As soon as the egg is laid (the female penguin lays one or two eggs at a time), the female drags for dinner and leaves the male to look at the nest. When the female returns (it may take up to two weeks for her to return), the man goes out for food, leaving the female with eggs.
  • Penguins are difficult to stay healthy in zoos due to the lack of biological protection against bacteria/germs found outside the cold Antarctic.
  • Penguins can eat up to 3,500 metric tons of squid, 115,000 metric tons of fish, and 1,500,000 metric tons of krill per year.
  • Penguins also have backward-facing bristles on the tongues, which helps slippery seafood to slip away.
  • The Emperor penguins are the only species that nests and breeds in Antarctica during the frigid winter.
    Leopard seals are the main threat to penguins, but sea lions and killer whales are also predators. Some large seabirds, such as the Australian eagle and Skua, also threaten the penguin.
    Penguins also have many on-land terrestrial predators, including cats, ferrets, foxes, lizards, mice, and snakes.
    Penguins can be at risk from water pollution, oil spills, and over-harvesting in the ocean.
  • Penguins also practice an annual fasting period during the breeding, molting, and preparedness for plumage feathers which takes 54 to 120 days depending on the species.
  • Survival is one of the main concerns for penguins. They make sure that there are no predators in their homes. They need to find a place where they will have sufficient food and shelter. They settle in a place that depends on the temperature of the climate. The water temperature must be at least 10 degrees Celsius or colder than their body temperature.
