We've all seen penguins before. Whether we've sent them at an aquarium like Sea world, or a photo on the internet, we've all heard of penguins. In The Moon By Whale Light, Ackerman goes on a group expedition to the cold land of Antarctica. While we've seen penguins waddle on land, we never really seen them in water. On land penguins are clumsy, mostly because they have no land predators to run from. Yet in the water, they are graceful and swift using their flippers to propel themselves through the water to catch fish and krill. One of the cool things about penguins is their color. Humans, who see in full color, are naturally drawn to black in white animals, like the panda, its just they way things are. For penguins, their white and black feathers are for protection. From above the black feathers look like just another black shadow on the ocean floor. Below, the white feathers look like just a glare from the sun, making it hard for predators to visibly see the pengiun. With all animals there are things that we are yet to discover, and if I were to get the chance to go to Antarctica to study penguins, I definitely would take the chance.
