Why do penguins have squat bodies?

Penguins have squat bodies that are well-adapted for their aquatic lifestyle. Their streamlined shape reduces drag while swimming, allowing for efficient movement through water. Additionally, their compact bodies help conserve heat in cold environments, as they have a layer of blubber and dense feathers that provide insulation. This body structure is essential for their survival in harsh climates and aids in their foraging for food underwater.
