Body
The chinstrap penguin, scientifically known as *Pygoscelis antarcticus*, typically reaches a length of 68–76 cm and weighs between 3.2 and 5.3 kg, with males generally larger than females. These penguins are recognizable by their distinct markings: a narrow black band under their head resembling a helmet, reddish-brown eyes, and a short black bill. Their face and chin are white, extending behind the eyes, while their flippers are black with white edges. The inner sides of the flippers and the underside of their body are also white, providing effective camouflage against predators when viewed from above or below in the water. Their legs are strong and pink, and their webbed feet aid in swimming, though on land, their movement is more of a waddle due to their stumpy legs. This countershading and their physical adaptations help them evade predators in their harsh aquatic environment.
