Penguins!

🐧 Penguins have more feathers per square centimetre than most birds.

🐧 Penguins can drink seawater because special glands remove excess salt.

🐧 Penguin bones are solid, not hollow, helping them dive deeper.

🐧 Penguins store heat using fat as well as trapped air in feathers.

🐧 Many penguins return to the exact same breeding site every year.
