Penguin
Penguins are, without any uncertainty, one of the most famous birds known to humankind. These flightless birds are aquatic in nature and reside in the Southern Hemisphere, Antarctica. Everyone is aware of these small black and white creatures, with the yellow tummy, all thanks to the innumerous films made on them. They stand around 3 feet tall and weigh 35 kg on an average. Their wings are more like flippers, which makes them the expert swimmers that they are. They hunt their prey underwater and raise their offspring on land.
