How Many Types of Penguins are There?
There are around 17 species of living penguins. There are other subspecies of penguins which are not added as a different type because of genetic similarity. Penguins live in the southern hemisphere whereas some species live in the Galapagos Islands near the equator.
Not every species of penguins live in Antarctica and frigid conditions. There are certain species which live in the temperate regions. The characteristics, features, size and look of the penguins varies from their habitation. Emperor penguins are the remarkable flightless marine bird which lives in Antarctica.
The following are the types of penguins,
- Emperor penguin:
It is the tallest and heaviest of all the living penguins. An adult emperor penguin can weigh to around 45 kg. And they stand tall up to 122 cm. Emperor penguins live in Antarctica. It is hard to differentiate between the male and female emperor penguins since they have similar plumage and size. The diet of the emperor penguins includes fish, squid, crustaceans and krill.
The dorsal part of the body is black including the head and has a white front. The yellow patches on each side of the ear make them spectacular. It is the only penguin species that can breed in the Antarctic winter. The blubber present in their body helps them stay in the frigid condition.
They can be on the underwater to about 18 minutes and recent researchers have found that they can stay at around 25 minutes underwater.
- King penguin:
It is the second largest after the emperor penguins. They can swim to the depth of more than 300 meter. King penguimeterseed on Sub-Antarctic islands and also in the temperate regions of South Georgia.
They stand about 70 to 100 cm tall and weighs maximum to 18 kg. Male king penguins are heavier than the females. The appearance of the king penguins is quite similar to that of the emperor penguins.
King penguins have bright orange patches on each side of the ear and white front. The lower bill and the neck have the same bright orange color. They prey on small fish, krill and squid. Their predators can be an aquatic mammal or seabirds.
- Adelie penguin:
Adelie penguins are habitual only to Antarctica. They are the best-suited species to compare with the tuxedo. Their black back and head along with the white front give a royal look of a tuxedo.
Being a mid-sized penguin, the Adelie penguin stands tall with the height of 71 cm and weighs maximum to 6.0 kg. They look unique with the white ring around the eyes. And also the black plumage covering the part of the bill Adelie penguins are distinctive from other species of penguins.
One of the unique facts about Adelie penguins is that they build a nest by using stones. They feed on Antarctic krill, ice krill, Antarctic silverfish, sea krill and glacial squid.
- Rockhopper penguin:
Rockhopper penguins are a species of penguins that come under crested penguins and they are sometimes described into three different species. Southern and northern rockhopper penguins have slightly different features from each other.
They are one amongst the smaller species of penguins. The males are bigger than the females. The adult rockhopper penguin can be of 20 inches height. The yellow and black spiky feathers on the head keep them unique from other species of penguins. They have a white belly and black body, red eyes and orange beak.
The categories of rockhopper penguins are,
- Southern rockhopper
- Northern rockhopper
- Eastern rockhopper
The southern rockhopper penguins are found in the Falkland Islands, Argentina, South America, Chile etc. The Northern rockhopper penguins are found in the cool regions of the Atlantic Ocean and certain islands of Indian Ocean. Eastern rockhopper penguins are found breeding in the Campbell Island in New Zealand.
Rockhopper penguins nest in the rocky coastlines irrespective of the subdivided species.
- Galapagos penguin:
Galapagos penguins live in the Galapagos Islands and it is the only species of penguins that live on the north of the equator. The adult Galapagos penguin stands with the height of 49 centimeters weighing around 2.5 kg.
They have a black upper part and white underparts. They have the white stripes over the eyes which meets the neck.
Because of their size they have many predators prey on them like crabs, snakes, rats, cats etc. Galapagos penguins are the second smallest penguins after the little penguins.
- African penguin:
The African penguin is also called jackass penguin and black-footed penguin. They are found near the African waters. They have a pink gland above its eyes which is used for the adaptation of changing temperature. They measure about 3.5 kg in weight and 70 cm tall.
The white plumage is visible from the sides of the head to the front body with a black band. They feed on fish and squid. The African penguins are also called the banded penguins. There are also other banded penguins in the Southern hemisphere, Magellanic and Humboldt penguins.
They are most commonly found in the south-western coast of Africa. The African penguins eat anchovies, squid, sardines and crustaceans. The predators of African penguins are fur seals, sharks, cats, caracals, mongooses etc.
- Yellow-eyed penguin:
It is the habitat of New Zealand. Yellow-eyed penguins are closely related to little penguins. It is a mid-sized penguin. The adult yellow-eyed penguin measure about 79 cm tall and weighs to a maximum of 8 kg.
The males are larger than the females. They usually nest in the forest or scrubs. They are commonly found in large bays. Yellow-eyed penguins are deliberated to be the world’s rarest species. They can be easily viewed by the tourists in the beaches of Oamaru, Dunedin etc.
- Humboldt penguin:
Humboldt penguins are the habitat of South America. They are similar to the Galapagos, Magellanic and African penguins. They are medium-sized penguins that grow up to 70 cm long and weighs up to 5.9 kg.
They have a fleshy bottom of the bill. The black head has the white line above the eyes and it runs to the neck and below. They have a white front body with a black band.
They nest near the rocky coast and build burrows in guano. Humboldt penguins are found on the Pacific coast along with the Magellanic penguins on the central Chilean coast. Humboldt penguins can also be found in many of the zoos around the world.
- Magellanic penguin:
Magellanic penguin is a South American penguin found in Chile, Argentina and Falkland Islands. And also sometimes these penguins migrate to Brazil. They are similar to the African, Humboldt and the Galapagos penguins.
Adult Magellanic penguins measure about 76 cm long and weigh around 6.5 kg. The males are larger than the females. They have a black back and white front. There are white and black bands present in the throat and belly. The black head has white stripes near the bill and bottom.
They prey on crustaceans, squid, cuttlefish and krill. An adult Magellanic penguin can dive up to 50 m deep to reach their food.
However they are found in Argentina and Chile even after threatened by oil spills.
- Erect-Crested penguin:
Erect-crested penguins are found only in New Zealand. They breed on Bounty and Antipodes Islands. They are small to mid-sized penguins. It has a black back and white front with yellow eye and crest. The adult Erect-Crested penguin stands tall up to 70 cm and weighs up to 6 kg.
Like other species of penguins the Erect-Crested penguin male is slightly heavier than the female. The yellow feathers over the eyes form the eyebrow with short feathers. They usually feed on krill and squid.
- Gentoo penguin:
Gentoo penguins have long-tail and they are found in the Antarctica regions of Tabarin Peninsula and the Falkland Islands. They are closely related to Adelie and Chinstrap penguins. Gentoo penguins can be easily identified by the white stripe on the head above the eyes along with the bright orange bill.
This unique identification helps to differentiate Gentoo penguins from other penguins. They have pale pink webbed feet. They measure about 90 cm long and weigh about 8.5 kg. They are the fastest swimming penguins. Gentoo penguins swimming speed is 36 km/h.
They breed in the ice-free planes in the Sub Antarctic Islands. Fish, crustaceans and krill are their major foods. Skuas, sea lions, killer whales, leopard seals, and giant petrels are the predators of Gentoo penguins.
- Chinstrap penguin:
Chinstrap penguins are found in the Southern Pacific and Antarctic oceans. They also have few different names like a ringed penguin, bearded penguin, stonecracker penguin. They produce a very loud call to communicate with other penguins and chicks.
Adult chinstrap penguin measures about 72 cm long and weighs about 5 kg. Male Gentoo penguins are taller and also heavier than the female penguins. They have a white front and black back.
The face has white coloration above the eyes and there is a black line on the face followed to the chin. The half black head and the combination of the white face looks like the Gentoo penguins wearing a helmet.
They prey on fish, squid, shrimp and krill. Predators of Gentoo penguins include leopard seal, killer whales, brown skua, and kelp gull.
- Fiordland penguin:
Fiordland penguins come under the crested penguin species and they are also called as Fiordland crested penguins. They are the habitat of New Zealand’s south islands and other outlying islands.
Fiordland penguins are medium-sized penguins with yellow crest and bluish grey upperparts and white body. They stand tall with the height of 60 cm and weigh about 5.95 kg. They are similar to the erect-crested penguins and Snares crested penguins.
They nest in the roots and rocks of the temperate coastal regions. They mainly feed on arrow squid, crustaceans and less of fish. The predators of Fiordland penguins are stoat, cats, dogs, and rats.
- Little penguin:
They are the smallest species of penguins. They are also called as fairy penguins, blue penguins or little blue penguins. Little penguins are found in the Southern Australia and New Zealand. They measure about 33 cm in height and weigh about 1.5 kg.
The head and the back are blue where the front body is white with the fading white color from the bill. The bill of little penguins measures about 3 to 4 cm long.
Little penguins are found largely in many of the Australian coastal regions.
- Macaroni penguins:
The macaroni penguins are found from the Sub-Antarctic to the Antarctic Peninsula. They are closely related to the Royal penguins and are one amongst the six species of crested penguins.
It has a unique yellow crest with the black head and white front body along with the bright orange bill and pale pink webbed feet. They also have a short feathered tail. They feed mainly on small fish, krill and crustaceans.

- Royal penguin:
They are the habitat of the South Antarctic and the adjacent islands. They are one of the crested penguin species. They measure about 75 cm long and weigh about 8 kg.
Royal penguins are found only in the Macquarie Island in the Pacific Ocean between New Zealand and the Antarctic. They look similar to the Macaroni penguins except that they have white face and chin.
They have a beautiful yellow coloration. Krill, crustaceans and small fish lie as their food.

Their main food is krill and the less of small fish and squid. Their predators are mainly sea lions, leopard seals, skuas, and petrels.
Penguins spend half of their life in land and half of their life in water. There are plenty of species that are extant. There are confusions in the subdivisions of the species of penguins.
The colonies are wide spread near the equator and also in the islands of southern hemisphere. The species of penguins features and characteristics depend upon the region.
