King penguin
The king penguin eats krill, small fish, squid, and plankton. In particular, they seem to enjoy eating lanternfish, which makes up most of their diet. They are able to dive to almost 300 meters (about 985 feet) for up to 15 minutes in order to catch their food. King penguins can also swim at 10 kilometers (6 miles) per hour, and their special eyesight helps them see in the dark.
