Chinstrap Penguin

Endemic to the rocky islands in Antarctica, the Chinstrap penguin is considered as one of the world’s smallest and most easily identifiable penguin species. As these penguins have a narrow black band under their head resembling the black helmet-wearing, they are called Chinstrap penguins.

The Chinstrap penguin is also called as the Ringed penguin or Bearded penguin for the same reason.

In this page, we’ll explore Chinstrap penguin facts, the IUCN status, its anatomy, diet, predators, life-span (in captivity and wild), how they sound & more.

Chinstrap Penguin Anatomy

Chinstrap Penguin

  • The maximum height that Chinstrap penguin can grow into is 72 cm.
  • A fully developed adult Chinstrap penguin weighs about 3 to 5 kg.
  • This species of penguin exhibits the sexual dimorphism like African penguins.
  • The white belly of Chinstrap penguins acts as a camouflage similar to Adelie penguins against the predators such as seals.
  • Underneath the feather coat, they have a firm layer of blubber (or fat) which helps in the extreme cold conditions to not to lose its body heat when swimming against the icy-waters. These evolutionary adaptations help them to survive in the Antartic regions.

Chinstrap Penguin Diet
