King penguins are majestic birds, but have you ever thought what do king penguins eat? As carnivores, king penguins primarily feed on small fish such as krill, squid, and lanternfish. Their dietary requirements are slightly different compared to other species of penguins.
The difference in the diet helps the penguins to survive by eating other kinds of fish in areas with growing penguin population. As the second largest penguin in size, only after emperor penguin, they need to eat a lot of fish to meet the energy demands of their body. King penguins measure around 70-100 cm and weigh anywhere from 11-16 kg.
