The blue whale has many adaptations that allow it to survive in its environment. The blue whale not only has blubber for warmth, and a streamline shape for swimming, but it is a mammal that lives in the water. The blue whale has an adaptation that does not allow it to sleep. If they slept, they would drown. So, they take short naps instead of long slumbers. The blue whale, to eat, has baleen plates that are used to filter the small shrimp-like krill that they feed on. Being mammals, they have also formed mammary glands to feed their young with. Being mammals allows the blue whale to have extended parental care for their young. Being so big, the whale has an extremely large fluke, which allows it to propel itself through the water at a decent speed, which can be about 30 miles per hour to escape dangerous situations. The blue whale's eyesight is good in the water, and out of the water but the sense that is the best is the hearing. They use vocalizations to communicate with other whales. Since they are under water, and the water is denser than air, it transfers sound fast and longer than air. These adaptations have made it easier for these large mammals to live in water as opposed to living on land.
