In the past..
In the past, people ate penguin eggs. They also killed adult penguins for their feathers, skin, and oil. People also used penguin droppings (guano) to fertilize the soil and help grow crops. While this seems harmless, some penguins use guano to make their nests. When the guano was gone, they had to lay their eggs on the bare ground, where they were more susceptible to predators.
Emperor Penguins are the largest penguins in the world and stand up to 4 feet (1.2 m) high and weigh as much as 100 pounds (45.3 kg).
Safety in numbers
Penguins usually enter and leave the sea in large groups. Scientists believe this is for “safety in numbers.” By blending into a crowd, an individual penguin may avoid catching the attention of a predator.
