  • Penguins are aquatic flightless birds that are highly adapted to life in water.

  • Their distinct appearance is called counter-shading which is a form of camouflage which helps

  • them keep safe in water.

  • In general, penguins love to eat krill, fish and squid however Penguins close to the equator

  • eat more fish than Penguins close to Antarctica.

  • Penguins can be found in every continent in the Southern Hemisphere from up close to equator

  • right down to Antarctica.

  • Penguins can spend up to 75% of their time in the water and they do all their hunting

  • in the water because their prey can be found within 60 feet of the surface so they have

  • no need to swim in deep water. Penguins catch their prey with their beaks and swallow them

  • whole as they swim.

  • Depending on the species, Penguins can live between 15 to 20 years.

  • Penguins tend to vary in size from the Blue Penguin which is the smallest Penguin species

  • that measures up to 16 inches tall to the largest Penguin which is the Emperor Penguin

  • which measures up to 3.7 feet tall and weighs in between 60 - 90 pounds.

  • Although they cant fly through the air with their flippers, many Penguins take to the

  • air when they leap from the water onto the ice. Just before they take flight, they release

  • air bubbles from their feathers which cuts the drag on their bodies and that allows them

  • to double or triple their swimming speed quickly and launch into the air.

  • Most species of Penguins swim underwater at around 4-7 mph, however the fastest Penguin

  • which is the Gentou, can reach top speeds of 22 mph.

  • Penguins don't have teeth, however they have backward facing fleshy spines that line the

  • inside of their mouths which help them guide their fishy meals down their throats.

  • Penguins are carnivores and feed on fish, squid, crabs, krill and other sea foods they

  • can catch whilst they are swimming. During the summer they eat much more heavily than

  • they do during the winter.During the winter they will just eat a third of what they will

  • eat during the summer.

  • Because they spend a lot of their time underwater, they take in a lot of salt water, however

  • they have a special gland which is a super orbital gland that is located just above their

  • eye that filters salt from their blood stream and is then excreted through the bill or by

  • sneezing.

  • Each year, Penguins experience a catastrophic moult where they lose the majority of their

  • feathers. They can't swim and fish during this time, so they fatten themselves up beforehand

  • to survive the two to three weeks it takes to replace them.

  • All but two Penguins species breed in large colonies for protection. These colonies range

  • from around 200 to hundreds of thousands of birds.

  • Penguins distinct appearance helps them keep camouflaged whilst swimming. From above their

  • black backs blend into the dark ocean water and from below their white bellies match the

  • surface of the bright sunlight. This helps them to avoid predators such as leopard seals

  • and hunt for fish unseen.
