Overview:

The main bird that can swim but can't fly is the penguin. Penguins are a remarkable gathering of birds principally tracked down in the Southern Half of the globe, with a huge number living in Antarctica. There are 18 types of penguins, going in size from the little Minimal Blue Penguin, otherwise called the Pixie Penguin, to the huge Head Penguin.

Penguins have advanced, unmistakable transformations that make them excellent swimmers. Not at all like most birds, penguins have wings that have changed into flippers. These flippers, alongside their smoothed out bodies, permit them to explore through water with surprising dexterity and speed. 

 

The failure to fly offsets their incredible swimming capacities. Penguins' bones are denser than those of flying birds, furnishing them with the vital counterweight to plunge profound into the sea. Moreover, their quills are firmly pressed and covered with oil from an organ close to their tail, which gives waterproofing and protection against the viral waters of their territories.

 

Penguins are additionally very much adjusted to life on the shore, where they breed, shed, and cooperate socially. 

 

The transformative compromise that prompted their flightlessness has permitted penguins to flourish in oceanic conditions.
