A pair of gigantoguin in captivity.

Gigantoguins are the largest species of penguin on earth, surpassing the killer penguin and the emperor penguin, being about 7 feet 4 inches tall and weighing about 235 pounds. Despite their size, they feed only on fish, squid, and crustaceans. They are one of the neighbors of emperor penguins, king penguins, Adélie penguins, and chinstrap penguins, rockhopper penguins, and macaroni penguins. Their anceators grew bigger to survive better from predators like ocras, killer penguins, etc.
