Penguin

 

Penguins are an indicator of the health of our watery planet, and if they are unable to survive, we had better take notice or we might find our own survival threatened. — Roger Tory Peterson

Penguins are flightless birds found in Antarctica, South Africa, Chile, Peru, Galápagos Islands, New Zealand and Australia. They have a streamlined body which helps them to swim fast. Most birds have bones which are hollow and filled with air. This anatomy helps them to stay light for flight. Penguins are an exception to this and they have solid bones which reduce buoyancy to stay afloat while swimming. A gland near the base of their tail provides waterproof oil which penguins use to cover their feathers before swimming. Thick feathers and oil helps the birds to stay warm. Penguins huddle together to protect themselves from predators. They are highly sociable animals and live in groups called rookery, colony and huddle. Many male penguins gift females rocks to build nests. The diet of these carnivorous birds includes squids, fishes and krills. Nearly half of the 18 species of penguins are listed as either vulnerable or endangered.
